DC MOTOR POSITION CONTROL BY DISCRETE-TIME VARIABLE STRUCTURE CONTROLLERS UDK: 62-504:62-501.41

Abstract: Discrete-time variable structure systems (DTVSS) with proportional, as well as with proportional-integral control algorithm have been presented. The properties of discrete time variable structure controller with proportional action (DTVSCP) and proportional- integral action (DTVSPI) for step response and external disturbances have been considered. The positional servo system (with DTVSP and DTVSPI) for ramp test signal has also been observed. The controllers were designed on the basis of the complete DC motor model. The object state variables were available for measurement. The design technique is illustrated by a simulated system
