Abstract: The problem of designing a switching controller for chattering attenuation in multi-model system is considered. Applying the method of eigenstructure assignment and the theory of model tracking, a set of multi-model switch controllers is designed to stabilize each subsystem and make the outputs of the closed-loop systems satisfy certain tracking performances. Output chattering is attenuated through selecting all the degrees of freedom provided by the method of eigenstructure assignment. A bank-to-turn (BTT) missile autopilot is designed by using the proposed approach. Simulation result shows the effect and validity of the proposed method in command tracking and switching chattering attenuations.

Key words: multi-model switching control, eigenstructure assignment, model reference, BTT missile
