Abstract :
We propose some simple methods for designing attachable robust compensators that improve the robustness and decrease the sensitivity of attached control systems. Concerning with the practical design method of robust model matching (RMM), we propose linear-time-invariant (LTI) attachable robust compensators for LTI control systems with some structured and unstructured disturbances. First, a generalized approach to the standard RMM is proposed. Then, a new configuration for RMM that separates the robust compensator from the existing controller is proposed. We also examine the efficiency of the proposed method by a laboratory experiment
