Multiple models robust adaptive controller of reduced model

The traditional robust adaptive control is easily trapped in transient performance. To solve this problem, a multiple models robust adaptive controller is proposed in this paper. For the adaptive control system with unmodeled dynamic, firstly, the regularization is used to convert the system unmodeled dynamic to bounded disturbance, and then, the multi-model robust adaptive controllers are designed based on system reduced model., finally, the BIBO stability and the boundness of the input output signal are proven. The simulation illustrates that the proposed method is preferable.
