摘要
为克服传统PID控制参数难以确定及PID参数对电机参数变化适应能力差的缺点,基于模糊控制技术,设计了基于模糊PID的直流电机双闭环调速系统;利用MATLAB仿真软件对基于模糊控制的直流调速系统性能进行了仿真研究,并和传统PID控制系统进行了比较。仿真结果表明,和传统PID控制比较,模糊控制系统超调量小、抗扰动能力强、鲁棒性更高,更具适应性,控制性能优越。
In traditional PID control, it is difficult to determine PID parameters and they have poor ability to adapt to change of the motor parameters. To overcome these defects,designs a DC motor double-loop speed control system based on fuzzy PID; the control system is simulated using MATLAB software, and it is compared with the traditional PID control systems. Simulation results show that the fuzzy control system has smaller overshoot of speed, stronger anti-disturbance ability, greater robustness, more adaptable,superior control performance, comparing with traditional PID control.
