Proposed presentation title: Transient-based fault diagnosis of electric motors based on the analysis of electrical signals

Abstract of the speech

Over recent years, traditional methods for condition monitoring of electric motors that rely on the analysis of electric signals (currents or fluxes) under steady-state have been complemented, and in some cases replaced, by modern methodologies relying on the analysis of these signals under steady-state operation of the machine. This talk explains the foundations of these techniques and the main advantages that they can provide (avoidance of false indications, higher reliability…). The main options for the application of transient-based diagnosis methods are exposed and several application examples will be commented.

Proposed presentation title: GA-Based Practical System Identification and Auto-Tuning for Multi-Axis Industrial Robots

Abstract of the speech

Fast-response and high-precision motion control is one of indispensable techniques in a wide variety of high performance mechatronic systems including micro and/or nano scale motion, such as data storage devices, machine tools, manufacturing tools for electronics components, and industrial robots, from the standpoints of high productivity, high quality of products, and total cost reduction. In those applications, the required specifications in the motion performance, e.g. response/settling time, trajectory/settling accuracy, etc., should be sufficiently achieved. In addition, the robustness against disturbances and/or uncertainties, the mechanical vibration suppression, and the adaptation capability against variations in mechanisms should be essential properties to be provided in the performance.

The keynote speech presents a practical auto-tuning technique based on a genetic algorithm (GA) for servo controllers of multi-axis industrial robots. Compared to conventional manual tuning techniques, the auto-tuning technique can save the time and cost of controller tuning by skilled engineers, reduce performance deviation among products, and achieve higher control performance. The technique consists of two main processes: one is an autonomous system identification process, involving the use of actual motion profiles of a typical robot. The other is an autonomous control gain tuning process in the frequency and time domains, involving the use of GA, which satisfies the required tuning control specifications, e.g., control performance, execution time, stability, and practical applicability in industries. The proposed technique has been practically evaluated through experiments performed with an actual six-axis industrial robot.

Proposed presentation title: Synthesis of RR and CC Dyads for Pick and Place Tasks with Guiding Locations

Abstract of the speech

A novel dimensional synthesis technique for solving the mixed exact and approximate motion synthesis problem for planar, spherical, and spatial dyads is presented. The methodology uses an analytic representation of the dyad's rigid body constraint equation in combination with an algebraic geometry formulation of the exact synthesis for three prescribed positions to yield designs that exactly reach the prescribed pick & place positions while approximating an arbitrary number of guiding positions. The result is a dimensional synthesis technique for mixed exact and approximate motion generation for planar RR, spherical RR, and spatial CC dyads. A solution dyad may be directly implemented as an open chain or two solution dyads may be combined to form a 4R or 4C closed chain; e.g. a planar four-bar mechanism. The synthesis algorithm only utilizes algebraic geometry and does not require the use of a numerical optimization algorithm or a metric on the elements of SE(2), SO(3), or SE(4); the groups of planar, spherical, and spatial displacements. Two implementations of the synthesis algorithm are presented; computational and graphical construction. Examples of the synthesis of planar four-bar, spherical four-bar, and spatial 4C mechanisms for pick and place tasks are included. Finally, applications and future works are discussed.

Presentation title: Fault Tolerance in Multiphase Electric Machine Drives

Abstract of the speech

Multiphase drives offer enhanced fault-tolerant capabilities compared with conventional three-phase ones. Their phase redundancy makes them able to continue running in the event of faults in certain phases, such as open- or short-circuit ones. Moreover, their greater number of degrees of freedom permits improving the performance not only under faults affecting individual phases, but also under those affecting the machine/drive as a whole. That is the case of failures in the dc link, resolver/encoder, control unit, cooling system, etc. Accordingly, multiphase drives are becoming remarkable contenders for applications where high reliability is required, such as electric vehicles and standalone/off-shore generation. Actually, the literature on the subject has grown exponentially in recent years. This keynote speech presents an overview about the state-of-the-art regarding fault tolerance in multiphase drives. The most important recent advances, emerging trends and open challenges are highlighted.

Presentation title: Expert Vehicle Control at The Limits of Handling

Abstract of the speech

Active chassis-control/safety systems have had an enormous impact in the global society and economy by achieving significant reduction of road traffic accidents, injuries and deaths. Several of these systems aim at delivering a stable, predictable and intuitive response of the vehicle for the average human driver. At the same time, expert human drivers in the field of motorsport, routinely operate their vehicles outside the envelope enforced by such active safety systems, to fully exploit the performance of the vehicle. In this presentation we discuss research work which aims to shed light into the optimality properties and performance benefits of driving techniques used by race drivers including extreme operating conditions which require expert skills. We also present a framework for the development of control algorithms able to stabilise the vehicle dynamics in such extreme conditions. Inspired by expert driving techniques a driver assist system concept for evasive manoeuvring is presented. Finally, in the context of driverless vehicles, the requirement for predictable and intuitive response of the vehicle for the average human driver becomes irrelevant. We envision that autonomous vehicle controllers will use expert skills to control the vehicle dynamics and operate outside the envelope enforced by current active safety systems if necessary. We present recent results in the development of autonomous vehicle controllers able to operate the vehicle at the limits of handling including their implementation on a prototype vehicle platform.

Presentation title: Modelling and robust control for steer-by-wire vehicles via sliding mode methodologies

Abstract of the speech

For automotive steer-by-wire (SbW) systems, system parametric uncertainties, nonlinearities (frictions, etc) and external disturbances (tyre self-aligning torque from road surfaces) exist and greatly make the control design to be quite challenging and difficult. In this talk, the mathematical modelling of the SbW system will be further explored and presented by an equivalent second-order dynamical system. Next, based on the derived simplified model of SbW system, a series of robust control schemes via sliding mode control (SMC) methodologies will be introduced, such that the robustness, good convergence property of steering tracking, and excellent disturbance rejection ability of the closed-loop SbW control system can be well obtained. Further, novel SMC-based yaw stability control schemes including upper and lower controllers are developed for SbW vehicles to improve the vehicle manoeuvrability and yaw stability performance. Hardware-in-the-loop and vehicle platforms are established, where fruitful real-time experiments are presented in support of the remarkable performance and effectiveness of the proposed schemes. Practical concerns surrounding the gaps between academia and industry on this topic are also reported.

Presentation title: Fault diagnosis and prognosis of steer-by-wire system based on finite state machine and extreme learning machine

Abstract of the speech

In this work, an integrated condition monitoring method combining model-based fault diagnosis and data-driven prognosis is proposed for steer-by-wire (SBW) system. First, the SBW system is modeled by bond graph (BG) technique and a twodegree-of-freedom (2-DOF) state-space model of the vehicle is built. Based on the 2-DOF model, the estimated selfaligning torque is used for the control of feedback motor. The fault detection is carried out by evaluating the analytical redundancy relations derived from the BG model. Since the fault isolation performance is essential to subsequent fault estimation process, a new fault isolation method based on finite state machine is developed to improve the isolation ability by combining the dependent and independent analytical redundancy relations, where the number of potential faults could be decreased. In order to refine the possible fault set to determine the true fault, a cuckoo search (CS)–particle filter is developed for fault estimation. Based on the estimated true fault, prognosis can be implemented which is important to achieve failure prevention and prolong system lifespan. To this end, an optimized extreme learning machine (OELM) is proposed where the input weights and hidden layer biases are optimized by CS. Based on data representing fault values obtained from the fault identification, the OELM model is trained for remaining useful life prediction of failing component. Finally, the proposed methodologies are validated by simulations.
