Abstract
A performance oriented three-loop control scheme is proposed, under the input and state constraints. The specific structure of the control scheme is that, an adaptive sliding mode controller is designed in the inner loop which is used to track the reference model replanted online, and the reference model is designed in the outer loop through using online optimization algorithm, in which the uncertainty and the state constraints are well considered. The bound of the disturbance is estimated in the middle loop, and is used in the design process of the reference model. The three loop controller can not only insure a steady performance, but also insure a fast convergence of dynamic performance. And the efficacy of the method is demonstrated through simulation.
