Abstract
In this paper, a new controller structure that deals with system responsein different frequency ranges is proposed. The proposed method is based on themulti-resolution theory that utilizes a set of filter bank to decouple a signalinto various frequency bands. After the frequency response of a dynamic systemis separated into specified ranges, the controller coefficients can he designedfor individual regions accordingly. With this proposed method, both tracking andtransient responses of the controlled system can satisfy the design criterion.ICIC International
