A discrete dynamic sliding mode control method for singular perturbation system such as the linear servo motor system is proposed in this thesis. The proposed new sliding mode control scheme consists two major parts. At the first stage, a discrete sliding mode control strategy for the singular perturbation system based-on the robust discrete sliding mode control approach is developed. Following, a discrete dynamic sliding surface design method that automatically generates the relative slope of the sliding surface at each sampling time is derived. Instead of the conventional fixed sliding surface approach, the dynamic surface one is proposed to increase the responding performance and to eliminate the chattering problems.
Experimental results illustrate that the new discrete dynamic singular perturbation sliding mode control strategy can be successfully applied to the precise positioning problem of a DC brushless linear motor system.
