摘 要：There is a certain type controller that has unknown and complex deterministic trend output of changing with time slowly in actual *** the traditional minimum variance criterion can’t be used to evaluate the stochastic performance of the controller *** this paper presents a method to address the difficulties in such case,which combines wavelet technology and minimum variance criterion for stochastic performance ***,wavelet technology(WA method) is adopted to separate stochastic portion from the output time *** then the stochastic portion is modeled and ***,stochastic performance of the controller is assessed based on traditional minimum variance *** effectiveness of the proposed method is verified through *** method can avoid over-differencing when the stochastic portion is extracted by using difference method(DI method),and realizes accurate and reliable assessment for stochastic performance of the controller.
