In this thesis we have presented sliding mode approaches to the problems of speed sensorless induction motor torque control and induction motor parameter adaptation. Such problems are commonly encountered in electric drives and many applications such as robotics, electric vehicles, and so on. The specific contributions of the thesis are: First, a new sliding mode flux/speed observer is developed by delicately introducing an auxiliary variable and a design parameter. Combining the sliding mode torque controller, we have thoroughly analyzed the convergence of the flux/speed observer and the asymptotic stability of the closed-loop system. Then, the robustness of the proposed sliding mode cascaded observer/controller scheme is effectively demonstrated by considering the effects of the variations of the rotor resistance, the stator resistance and the load torque. Finally, we have proposed a sliding mode rotor resistance adaptation scheme in the same framework. This scheme overcomes all the limitations of the conventional motor parameter adapatation methods.

Apply Sliding Mode Theory to Solve Control Problems Interest in SMC has grown rapidly since the first edition of this book was published. This second edition includes new results that have been achieved in SMC throughout the past decade relating to both control design methodology and applications. In that time, Sliding Mode Control (SMC) has continued to gain increasing importance as a universal design tool for the robust control of linear and nonlinear electro-mechanical systems. Its strengths result from its simple, flexible, and highly cost-effective approach to design and implementation. Most importantly, SMC promotes inherent order reduction and allows for the direct incorporation of robustness against system uncertainties and disturbances. These qualities lead to dramatic improvements in stability and help enable the design of high-performance control systems at low cost. Written by three of the most respected experts in the field, including one of its originators, this updated edition of Sliding Mode Control in Electro-Mechanical Systems reflects developments in the field over the past decade. It builds on the solid fundamentals presented in the first edition to promote a deeper understanding of the conventional SMC methodology, and it examines new design principles in order to broaden the application potential of SMC. SMC is particularly useful for the design of electromechanical systems because of its discontinuous structure. In fact, where the hardware of many electromechanical systems (such as electric motors) prescribes discontinuous inputs, SMC becomes the natural choice for direct implementation. This book provides a unique combination of theory, implementation issues, and examples of real-life applications reflective of the authors’ own industry-leading work in the development of robotics, automobiles, and other technological breakthroughs.

This book describes the advances and applications in Sliding mode control (SMC) which is widely used as a powerful method to tackle uncertain nonlinear systems. The book is organized into 21 chapters which have been organised by the editors to reflect the various themes of sliding mode control. The book provides the reader with a broad range of material from first principles up to the current state of the art in the area of SMC and observation presented in a clear, matter-of-fact style. As such it is appropriate for graduate students with a basic knowledge of classical control theory and some knowledge of state-space methods and nonlinear systems. The resulting design procedures are emphasized using Matlab/Simulink software.

The main objective of this monograph is to present a broad range of well worked out, recent application studies as well as theoretical contributions in the field of sliding mode control system analysis and design. The contributions presented here include new theoretical developments as well as successful applications of variable structure controllers primarily in the field of power electronics, electric drives and motion steering systems. They enrich the current state of the art, and motivate and encourage new ideas and solutions in the sliding mode control area.

The book Applications of Various Fuzzy Sliding Mode Controllers in Induction Motor Drives contains publications on various fuzzy sliding mode speed controllers (FSMCs) based on the boundary layer approaches in the area of an indirect field-oriented control (IFOC) for Induction Motor (IM) drive, which include development and implementation FSMCs and related ?elds. The publications within Applications of Various Fuzzy Sliding Mode Controllers in Induction Motor Drives cover signi?cant and recent developments of both foundational and applicable character in the field. With the exception of some basic notions in sliding mode control (SMC), field-oriented control (FOC), and fuzzy theory, the book is completely self-contained. Important concepts in FSMCs and its use in high performance IM are carefully motivated and introduced. Specifically, the authors have excluded any technical material that does not contribute directly to the understanding of SMC, FOC or fuzzy theory. Many other excellent textbooks are available today that discuss fuzzy, FOC and SMC in much more technical detail than that which is provided here.

Abstract: Induction machines are widely used in industry application. Consequently more and more attention has been given to design and development of induction machine control. High performance of induction machine control is achieved by so called field orientation control (FOC). Speed sensorless technology has also been proposed for decades to overcome the disadvantages of cost and fragility of a mechanical speed sensor. However, due to the high order, multiple variables and nonlinearity of induction machine dynamics, the development of advanced induction machine control is still a challenging task. In this research, a sliding mode based flux and speed estimation technique for speed sensorless control of field oriented induction machine is first investigated. The parameter sensitivity of the control method is also analyzed. A robust sliding mode speed controller is also presented, which has the advantage of disturbance rejection and avoiding re-tuning gains comparing to traditional PI controller Then an adaptive sliding mode observer is proposed and the stability is verified by Lyapunov theory. Two sliding mode current observers are utilized to compensate the effects of parameter variation on the rotor flux estimation, which make flux estimation more accurate and insensitive to parameter variation. The convergence of the estimated flux to actual rotor flux is proved by the Lyapunov stability theory. Finally, an efficiency optimization method which does not require extra hardware and is insensitive to motor parameters is presented. The relationship between stator current minimization and motor loss minimization in the induction motor vector control system is investigated. A fuzzy logic based search method is simulated and implemented. It is determined that the motor loss minimization can be achieved by minimizing stator current in practice. An experimental setup is presented in the appendix to verify the proposed approaches. The simulation and experimental results are presented to demonstrate the potential and practicality of the presented approaches.
