This volume presents the theory and application of Sliding Mode Control in Synchronous Drives. It demonstrates the methodology of control design and the original algorithms of control and observation. Practically all semiconductor devices are used in power converters, that feed electrical motors, as power switches. A switching mode offers myriad attractive, inherent properties from a control viewpoint, especially a sliding mode. Sliding mode control supplies high dynamics to control plants, invariability of systems to changes of their parameters, and of exterior disturbances in combination with simplicity of design. Unlike linear control, sliding mode control does not replace the switching control plant, but uses this natural feature of the control plant effectively to ensure high control quality.
This is the first text that thoroughly describes the application of the highly theoretical control design approach to synchronous drives in practice. It examines in detail the different features of various types of synchronous motors and converters with regard to sliding mode control design. It further presents a detailed analysis of control issues and mechanical coordinate observation design for various types of synchronous motors, of power converters, an various drive control structures. It also discusses the digital implementation of control, observation and identifi cation algorithms. 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 advanced students who work in the field of electric drive control. It is also recommended to experts in control theory application, who work with sliding modes for the control of electrical motors and power converters.
