Abstract :
In this paper we designed a Fractional order controller for level control system. Based on experimental model of the process, the different tuning rules have been computed and compared in order to minimize the integral square error with a constraint on the maximum sensitivity. To assess the controller performance with achieved performance, we tested the robustness of the system for process model stability. By comparing the results obtained for integer order controller (IOC) and fractional order controller (FOC), it is shown that fractional order controller gives better result for an obtained process model.
