✦ Synopsis

m method is proposed to optimal-tune the parameters of PID controllers. DifJerent from traditional techniques, the tunin 9 procedure of the proposed method is described in terms of fuzzy rules, in which the input variables are the error signal and its derivative, and the output variables are the PID parameters. A 9enetic algorithm (GA) is then used to search.for the optimal PID parameters that will minimize the integral of the squared error. In the simulation examples, comparison between the proposed method and other tunin 9 techniques is made. In addition, simulation is also carried out on a ball and beam system to show the application of the proposed method to nonlinear systems.

A simple method for the automatic tuning of PID controllers in closed loop is proposed. A limit cycle is generated through a nonlinear feedback path from the process output to the controller reference signal. The frequency of this oscillation is above the crossover frequency and below the critical f
