Grinding wheel dynamic balance control system based on the sliding mode variable structure

This article studies a kind of grinding wheel dynamic balance control device sliding variable structure controller based on the grinding wheel dynamic balance observation system mathematical model. It has proposed a new kind of method for improving the dynamic performance of balance block control system, which applies variable structure control theory and quoted non-linear switching function and has solved the problem of slow responsible speed of linear switching function. The simulation result indicates that the sliding mode variable structure controller with non-linear switching function can greatly improve system dynamic performance, and can also guarantee system static error fluctuation in permitting scope, so it can satisfy the contradictory request between the fast dynamic response and prohibition of over-regulation.
