摘　　要：针对传统PID控制器不能满足直流调速系统动态性能要求,无法获得调速系统较高的控制精度的不足之处,在没有建立精确的直流电机调速系统的数学模型情况下,对调速系统转速外环采用准PR控制器,电流内环采用经典的PI控制器的双闭环反馈控制,不仅满足了系统的稳定控制精度的要求,而且提高了系统的动态响应性能。经过对比仿真结果表明,采用的控制方法能够较好克服传统PID控制器存在的不足,减小了系统的超调量,改善了系统的动态响应速度,对直流电机调速控制系统的性能优化问题具有一定的实用价值。In view of the deficiency of traditional PID controller cannot meet the requirement of DC speed control system dynamic performance and get a higher control precision of speed control system, the speed regulation system adopting QPR controller for speed loop and classical PI controller with double closed loop feedback control for current inner ring are studied without establishing accurate mathematical model of DC motor speed regulating system. This speed regulation system can not only satisfy the control accuracy of system stability, but also improve the dynamic response performance of system. The comparison of simulation results shows that the control method can overcome existing deficiency of traditional PID controller, reduce the overshoot of system and improve the dynamic response speed of system. This study has certain practical value on performance optimization of DC motor speed control system.
