Study of Double Closed Loops Fuzzy Adaptive Control Method of Brushless Direct Current Motor
摘要
Abstract
Based on the mathematical model of brushless direct current motor, double closed loops control method was proposed. Current loop is the inner loop of system and PI control is adopted. Speed loop is the outer loop and PI control combined with fuzzy control is adopted, that is fuzzy adaptive control. Take speed error and speed error derivative as the input of fuzzy controller. Fuzzy control strategy is adopted to enhance the system response speed and robustness when the speed error is big. PI strategy is adopted to make the system have no steady-state error when the speed error is small. Simulation and experimental results show that double closed loops fuzzy adaptive control system has good dynamic and static performance, and strong robustness compared with traditional PI control system.关键词
