Application of Sliding Modes to the Control of Electric Drives
This paper presents the basic results of the research aimed at finding out what are the potential applications of the sliding mode in the control system synthesis of AC and DC motor drives. The general method for design of control systems with "deliberately introduced" sliding mode motion can be divided into two steps: the first - selection of desired character of the control process and selection of functions that describe descrepiancy from the desired process, the second: - selection of the control vector such that the functions that describe descrepiancies are equal to zero. A design approach, based on this method, for the design of control systems of both DC and AC machines is presented in the paper. Similarities between the algorthms are pointed out.
