Sliding Mode Control for Synchronous Electric Drives

This volume presents the theory and application of control systems with sliding mode in electrical motors and power converters. It demonstrates the methodology of control design and the original algorithms of control and observation. As practically all current semiconductor devices are used in power electronics as power switches, switching comes with myriad attractive, inherent properties from a control point of view. Sliding mode control systems supply high dynamics to systems, invariability of systems to changes of parameters, and exterior loads in combination with simplicity of design. Unlike linear control, switching sliding mode control does not replace the control system, but uses the natural properties of the control plant system effectively to ensure high control quality. Examining in detail the different features of various types of synchronous machines and converters with regard to sliding mode control design, this book presents a detailed analysis of control issues and mechanical coordinate observation design for various types of synchronous machines and various drive control structures. It also discusses drive parameter identification. The potential of sliding mode control and observation are moreover demonstrated in numerical and experimental results from real control plants. This work is intended for professionals and advance students who work in the field of electric drive control. It is also beneficial to experts in control theory application, particularly in the use of sliding modes for the control of electrical motors and power converters.
