The use of relay shifting method of process identification for auto tuning of PID controller
Original language description
The paper describes the use of a recently published method of relay feedback identification (called the shifting method) for estimation of the second order time delayed system model. An algorithm is designed for estimation of model parameters from two points of the frequency characteristics of the identified system. Both points are obtained from a single relay feedback test without any assumption about the model transfer function. The relay shifting method used here was modified by using an integrator in the feedback loop or an added time delay in closed loop. It allows to estimate points of frequency characteristics in positions more suitable for model fitting than the original shifting method approach. This modification enables a better estimate of the static gain even under constant load disturbance. The identified process model was used to calculate the PID controller parameters. The proposed solution is demonstrated on simulated and real examples.
