According to the sliding mode variable structure theory, a design method of speed regulator is proposed. The speed regulator by the sliding mode controller and integral part 2 parts. Through the rational selection of the slope C of the switching function, the regulator scale factor Ψ1 and the integral factor Ψ2, and the related parameters α1, α2 and β1, β2, the slip, position and velocity of the three-loop AC position servo system Modulus structure control strategy, with no overshoot positioning, no static error, fast response, robustness and so on. And using Matlab 5.0 simulation experiments, to verify.
