ABSTRACT The paper mainly studies the variable structure adaptive control theory for uncertain systems, and applicated the theory into the designs of bank-to-turn missile autopilots. The main contributions of the paper are as follows:(1) Under the condition that all the matched or mismatched parameter, input and disturbance uncertainties exist, a complete set of variable structure control system design and analysis method is proposed and investigated, which brecks throush the serious confines of variable structure invariance conditions theoretically and widen the application area of the VSC theory greatly.
