Abstract :
Performance assessment and monitoring of control system can be used to improve the performance of industrial process. Combined with a robustness index of a SISO control system, this paper presents a robustness assessment method based on relay feedback, which is able to conduct in-depth analyses in frequency domain according to the Nyquist curve. Simulation results have shown the effectiveness and feasibility of this method
