Performance assessment and controller design for unknown systems based on gain and phase margins using modified relay feedback

چکیده
A systematic procedure for performance assessment and PI/PID controller design based on modified relay feedback test is proposed in this paper. It can estimate the gain and phase margins of unknown systems on-line to indicate the appropriateness of the controller parameters. When the retuning of controller is found necessary, the proposed modified relay feedback scheme can be applied to tune the PI/PID controller based on specifications of gain and phase margins. Performance assessment and controller design can be done simultaneously, which ensures a good performance of the control system.

Performance Assessment for Completely Unknown SISO and MIMO Systems Based on Gain and Phase Margins Using Modified Relay Feedback
A performance assessment procedure for single-input-single-output (SISO) and multi-input-multi-output (MIMO) systems based on modified relay feedback test is proposed in this paper. The well-known robustness measurements, gain and phase margins, are used to assess the performance of the control systems. The proposed method can on-line estimate the gain and phase margins for systems with both un...
