Abstract: This paper presents a new applicationof the genetic
algorithmfor the selection of the variablestructure controller
(VSC) feedback gains and switching vector for a separately
excited DC motor. Contrary to the VSC design methods
reported in the literature, the present method provides an
optimal and systematicdesign procedure for the selection of
the feedback gains and switching vector. By the -proposed
VSC controller,the speed of a tested DC motor followsa pre-
determined speed track to a high degree of accuracy. The
proposed controller has been found robust against high
variationsin the motorparameters.
DC drive systems are often used in many industrial
