A frequency domain PID controller design method for integrating processes with dead - time in modified Smith predictor
نویسندگان
چکیده
In this paper a new PID controller design method in a modified Smith predictor configuration is proposed for integrating processes with dead time. A two-degree-of freedom control scheme has been considered where first a controller is designed to achieve the desired set-point response and then the load-disturbance rejecting controller is computed. Both the controllers are designed using the direct synthesis approach in frequency domain. The obtained Smith predictor controllers are converted into PID form by frequency response matching of the respective controllers at two low frequency points. The efficacy of the method is demonstrated through simulation of examples taken from the literature and the performance is compared with some of the prevailed methods.

Abstract: This paper presents a new method for a PID-control design in which the PID-control loop is represented as an equivalent one to a control loop operating with an optimized PI-controller and a Smith predictor. It requires the nearest approximation of the power plant process description and the dead-time transfer function. The presented method is based on the PID-controller transfer funct...
