Robust Control Systems for Modern Power Electronics: Applications and Challenges
Speaker: Doctor Sajjad (Fekri) Fekriasl

Power electronics has had rapid development in the last decade and is currently used in wider real-life applications. Along with the above, Power Electronics also lays the foundations of our future life by providing us with alternative, long-term solutions for environmentally clean renewable energy resources. While a variety of power converter topologies have been already developed, many novel and complex topologies are designed every day. However, the bulk of their control systems are mostly remained in the “tuned” traditional controllers such as PIDs; such controller is actually tuned for the nominal operational condition, and thus may not yield satisfactory performance (or even stability) for the full envelope of converter operating conditions. In addition, there are inherent perturbations in the power converter systems that cannot be addressed by these tuned controllers. Electrical elements (parametric) uncertainties, transportation and computational (complex-valued) delays, load variations, voltage source distortions, unmeasured external disturbances and sensor noises are examples of such perturbations. Advanced robust controller design techniques can aid development for new converter systems with guaranteed stability and improved performance. In addition, they offer clear design guidelines so as to reduce the cost and size of converters. The goal of this talk is to review and discuss the applications of advanced robust control systems in challenging power electronics systems. Some of the results including fast DC converters for Electrical Vehicles battery charging systems will be presented and discussed, along with the future directions of power transmissions and renewable power sources applications, such as HVDC, Wind power and Solar photovoltaic (PV) systems.

Sajjad has co-authored more than 35 technical articles including book chapters and invited articles. His current research focus is on the theory and application of robust control systems for modern power electronics applications, with an emphasis on synthesis of multivariable control systems, mu synthesis and software, and linear and nonlinear estimation.

Industrial application of condition monitoring and diagnosis - prospects and pitfalls?
Speaker: Doctor Alexander Horch

There is a considerable gap between academic research and industrial practice in the area of fault detection, fault isolation and fault-tolerant control. Reasons for this are manifold and will be discussed based on concrete examples from industry. On one side there are increasing requirements on operational excellence in process plants. On the other side there is only a minimal workforce available for operation and maintenance. Automation of fault detection and isolation on one side and fault-tolerance on the other side should therefore be self-evident. They are, however, not. The talk will discuss reasons for this and show examples from industry where those obstacles have been overcome. As a consequence, some possible directions for academic research as well as success criteria will be pointed out.

Adapting dynamic reliability from probabilistic safety analysis to fault-tolerant control?
Speaker: Professor Pierre-Etienne Labeau

Dynamic reliability is a general modeling framework that allows to accounting for the hybrid (i.e. discrete-continuous) nature of reliability and safety problems. It actually originates from the fields of probabilistic safety analysis, a.o. for nuclear power plants, and from attempts at accounting for control devices in system reliability theory.
The proposed talk aims to review the concepts and methodology of dynamic reliability and their potential applications to fault-tolerant control and other applications.

Curriculum vitae - Pierre Etienne Labeau

Fault tolerant control using Gaussian processes and model predictive control
Speaker: Professor Jan Maciejowski

Essential ingredients for fault-tolerant control are the ability to represent system behaviour following the occurence of a fault, and the ability to exploit this representation for deciding control actions. Gaussian processes seem to be very promising candidates for the first of these, and model predictive control has a proven capability for the second. We therefore proopose to use the two together to obtain fault-tolerant control functionality.

LPV methods for fault-tolerant vehicle dynamic control
Speaker: Professor Olivier Sename

This talk aims at presenting the interest of the Linear Parameter Varying methods for vehicle dynamics control, in particular when some actuators may be in failure. The cases of the semi-active suspension control problem and the yaw control using braking and steering actuators will be presented.
In the first part, we will consider the semi-active suspension control problem, where some sensors or actuator (damper leakage) faults are considered. From a quarter-car vehicle model including a non linear semi-active damper model, an LPV model will be described, accounting for some sensors/actuators fault represented as some varying parameters. A single LPV fault-tolerant control approach is then developed to handle the system performances and constraints.
In the second part the synthesis of a robust gain-scheduled $H_\infty$ MIMO vehicle dynamic stability controller (VDSC), involving both steering and rear braking actuators, is proposed to improve the yaw stability and lateral performances. An original LPV method for actuator coordination is proposed, when the actuator limitations and eventually failures, are taken into account. Some simulations on a complex full vehicle model (which has been validated on a real car), subject to critical driving situations (in particular a loss of some actuator), show the efficiency and robustness of the proposed solution.

Challenges, Opportunities, and Developments on Fault-Tolerant Control with Applications to Autonomous Unmanned Systems
Speaker: Professor Youmin Zhang

Unmanned systems including Unmanned Aerial Vehicles/Systems (UAVs or UASs), Unmanned Ground Vehicles (UGVs), and Unmanned Surface/Underwater Vehicles (USVs/UUVs), etc. are gaining more and more attention during the last few years due to their important contributions and cost-effective applications in several tasks such as surveillance, sense, search, rescue, geographic studies, military and security applications. On the other hand, health management and fault-tolerant control of manned aerial vehicles have a long history since the initial research on self-repairing flight control systems in US Air Force and NASA begun in mid-1980s. However, due to safety concern of manned aerial vehicles to the pilot, experimental tests and further practical research and development have been limited. Benefited from the recent and significant advance and development of UAVs, development and application of autonomous, fault-tolerant, as well as cooperative control techniques have been emerged and developed quickly in recent years, since UAVs provide a cheap and operative experimental testbed for development, implementation, testing and validation of the newly developed autonomous, fault-tolerant, as well as cooperative guidance, navigation and control techniques.
In this talk, a brief review on the development of fault-tolerant control techniques in the manned aircraft systems will be presented firstly, then the challenges and opportunities on autonomy and fault-tolerant control of unmanned systems will be given secondly, and finally the latest developments and current research work in this active research and development area with applications to autonomous fixed-wing and rotary-wing UAVs will be introduced.
