An intelligent optimization method for designing PID controllers based on particle swarm optimization (PSO) is presented in this paper. The conventional gain tuning of PID controller (such as Ziegler-Nichols (ZN) method) usually produces a big overshoot, and therefore modern heuristics approach such as genetic algorithm (GA) and particle swarm optimization (PSO) are employed to enhance the capability of traditional techniques. However, due to the computational efficiency, only PSO will be used in this paper. The performance comparison of the ZNPI and PSO based PI controllers are compared based on performance indices like maximum peak overshoot, settling time, Integral Square Error (ISE) and integral absolute error (IAE). The proposed PSO based PI controller is tested on the chosen Horizontal Cylindrical Tank level system and better controller performance can be envisaged by in the proposed methods than that of the ZNPI controller.
