Abstract

Modern control techniques of electrical drives (EDs) use robust control algorithms. One of such algorithms is variable
structure control (VSC) with sliding mode (SM). SM control needs more information on the controlled plant than the conventional
PI(D) control. Valid mathematical model of the controlled plant is necessary for the SM controller design. Generalized mathematical
model of two-phase electrical machine and its adaptation to direct current (DC) and induction motor (IM) are given in this paper,
employed in the cascade control structure. Also, the basic SM control theory and discrete-time controller design approach, developed
by the authors, are given. Finally, experimentally realized examples of speed and position control of DC and IM are given as an
illustration of the efficiency of the promoted EDs controller design via discrete-time VSC.
