Research on the Step by Step Sliding Mode Variable Structure Adaptive Control

Abstract:

In order to increase the control precision in meeting the robust request, a step by step sliding mode variable structure adaptive control strategy is presented in accordance with kind of two order time-invariant controlled object. Because the chatter amplitude is decreased when the system cuts in the position of equilibrium by the small peak-to-peak value, the mathematical model is firstly established and using the adaptive algorithm determined the control quantity to achieve the target value, then uses by the step by step method about, in the proper attention to both rapidity and robustness, reduces the peak-to-peak value deviation gradually which cuts, thus obtains the high control precision.
