This paper presents a new approach for tuning PID controller. However, the PID controller has advantages such as: a good response, the simple structure and robustness of method, but it has disadvantages such as: optimally tuning gains of PID have been quite difficult and it cannot adapt a non-linear state of plant. In this paper a hybrid of PSO and TLBO is proposed for autotuning a PID. The results demonstrate Superior performance of proposed method in comparison with other PID controller.
