Abstract: The typical nonlinear interacting tank process has the difficulty in controller design because of a change in system dynamics and interaction of processes. This paper deals with design methodology of state feedback with and without integral controller and the performance of which is compared with ZN tuned PID controller. A simulation is carried out using MATLAB to control the modeled nonlinear interacting tank processes.
Keywords: Interacting tank process, PID controller, State feedback controller.
