摘要
转速反馈控制系统用PI调节器实现了无静差调节,并用电流环限制了电枢电流,消除了负载转矩扰动对稳态转速的影响,实现较好的动态过程.虽然其动态性能可以满足一般工业需求,但是对于最动态性能要求高的场合,传统的双闭环就无法满足要求.结合内模控制原理,提出了一种新型PID转速调节器,使系统具有更好的动态性能.经过MATLAB/SIMULINK仿真,结果表明控制系统能稳定运行在目标工作点,并且相比于传统的双闭环调速系统具有更好的动态性能和抗扰动性能.
With the feedback of speed control system ,we use PI adjuster to realize zone-error adjustment and eliminate the influence of disturbance of load torque on speed ,and use current loop to limit the cur-rent of armature , realizing the better dynamic quality .Although its dynamic quality can meet the common needs of industries , the traditional double closed loop are not satisfied in the occasions which request high dynamic properties .This article puts forward a new PID speed adjuster to make the speed regulation sys -tem has a better dynamic property according to the principle of internal model control （IMC）.The result of the simulation on MATLAB shows that the control system can work at the point of destination steadily , which has a better dynamic property and disturbance-resistant performance than the traditional speed reg-ulation of double closed loop .
