Abstract: S plane control is designed based on the fuzzy logic control and the form of PID control, which is a simple and effective method, but its control parameters must be adjusted manually. The control precision and effect may be reduced if the parameters of S plane controller are improperly set. A method for optimizing the control parameters of S plane based on the modified simulated annealing algorithm is proposed. The simulated annealing algorithm is improved through the selection of initial temperature, annealing algorithm, memory function, stop temperature setting, etc. The control parameters of S plane can be adjusted and optimized automatically using the algorithm. The experimental results show that the improved S plane controller based on the simulated annealing optimization possesses higher precision and quicker response compared with the traditional S plane controller.
