Abstract

Electrical machines are supplied with electric power, therefore some modulation of electric power is required for control of them. This modulation is mainly achieved by PWM (Pulse Width Modulation), in which continuous signal is represented by the sequence of "ON" and "OFF" signal. However, any attention has not been paid to this modulation from the control point of view. The control systems of electrical machines should be optimized including the power modulation parts. VSS (Variable Structure Systems) are suited for such systems as require some modulation of electric power, because they are essentially based on discontinuous control. Motion control systems using electrical machines are designed to be robust by VSS taking discontinuous signals of VSS as "ON" and "OFF" of switching devices. In this paper, validities of VSS applying to electrical machines are discussed based on experiments of actual plants.
