Abstract

In the present paper, characteristics of transient processes, appearing in an unstationary armature controlled de electric drive system, are studied. The study here is based on realizing in the system, a mode closely similar to the sliding modes, in the contour of speed. The derived control algorithm is based on the fact that, there is no complete information about the system state variables.
 A mathematical model for a ningth order electro-mechanical system is represented. The designed regulator insures the invariance property of the system, against the internal disturbances, resulting from parameters variations. Computing results, provide a new trend for the possibility of practical utilization of variable structure contra methods in electro-mechanical systems.
