摘要
Luyben proposed a procedure for system identification based on the relay feedback system. This approach can lead to significant errors in the system parameters for transfer functions with time delay. Analytical expressions for the period of oscillation and amplitude ratios are derived. On the basis of these expressions, a procedure is proposed for deriving transfer functions. The results show that improvement can be achieved using the proposed method.
