A New Controller Design Method for Single Loop Internal Model Control Systems

Abstract

In the present developed work, a new controller design methodology of Internal Model Controller has been proposed for improving the closed-loop response. The IMC controller has been viewed into its gain and dynamic parts. The key strategic difference is that the controller dynamic part has a generalized structure. The designer has the choice to select between low and high-order controllers to outfit the control applications better. The controller order has been considered in terms of simple first/second-order type, and the design guidelines are presented. As in the case of the traditional IMC controller, there is principally a single variable parameter in the developed IMC controller, which can be monotonically tuned to meet the compromise between achievable performance and the stability of a closed-loop system. The merits and applications of the developed IMC controller design methodology for high-order systems have been evaluated using several simulation examples.
