The reaching period eliminating circuit of the variable structure controller

摘要

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reach period elimination circuit for a variable structure controller, _One(O), there is a certain arrival time to reach the switching plane. During this period, the origin convergence state of the system is sensitive to external disturbance and parameter fluctuation applied to the system, and the stability of the origin reception of the system is unstable there was. In order to solve this problem, in order to solve this problem, another switching plane is set on a position axis where an initial state of the system is placed, and the arrival period is eliminated by two switching planes, And the arrival time control circuit of the variable structure controller.
