A PSO Approach for Optimum Design of Multivariable PID Controller for nonlinear systems (1306.6194v1)

Abstract: The aim of this research is to design a PID Controller using particle swarm optimization (PSO) algorithm for multiple-input multiple output (MIMO) Takagi-Sugeno fuzzy model. 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 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 results show the advantage of the PID tuning using PSO-based optimization approach.
