Abstract
In order to reduce the design and structure complexity and chattering of the traditional sliding mode controller, a compound control method combining exact feedback linearization and quasi-sliding mode variable structure control was proposed and applied into active power filters (APF). On the basis of the affine nonlinear model of three-phase shunt APF in the synchronous d-q frame, the nonlinear coordinate change matrix and the state variable feedback equations were derived, and then an exact feedback linearization model was constructed. An integral sliding mode function was designed in terms of linear systems, and the existence of equivalent control and accessibility of sliding mode control were proved. Finally the quasi-sliding mode controller was constructed and the range of parameters was determined. The results of simulations and experiments show that this compound control has the advantages of both exact feedback linearization and sliding mode control. This method has flexible dynamic control response and excellent stable control performance with chattering suppression.关键词
