Abstract: In this paper, Hybrid Particle Swarm Optimization and Tabu Search (HPSOTS) is proposed to automatically generate Fuzzy Controller for MIMO systems. The algorithm is used to simultaneously optimize the premise and consequent parameters of the fuzzy rules for the appropriate design of fuzzy controller for Takagi-Sugeno zero-order. Solution found after each step of PSO algorithm was introduced in Tabu search algorithm as initial solution to seek its best neighboring solution. This hybridization of global and local optimization algorithms minimizes the number of iterations and computation time while maintaining accuracy and minimum response time. The algorithm was tested to control two nonlinear dynamical MIMO systems. Results proved the effectiveness of the proposed algorithm.
