Switched system controller design: The frequency domain approach

Abstract

The paper deals with the frequency domain switched system controller design for SISO plants with arbitrary number of operation modes. The proposed method combines affine model of the switched system, gain scheduling approach, and the Small gain theory modified so as to guarantee closed-loop stability of the plant in all operation modes as well as of the switching process between individual modes. A simple example is provided to illustrate the innovative approach and compare it with the Explicit MPC controller design.
