基于Simulink的双闭环直流调速系统设计

Design of Double-loop Direct Current Control System based on Simulink

研究了双闭环直流调速系统的结构.根据系统结构,按照由内到外的顺序分别设计电流调节器和转速调节器.为使系统无静差,两个调节器均选为PI调节器.在用Simulink仿真的过程中,对调节器参数进行了整定,使系统达到稳定状态.通过仿真曲线,说明了设计的合理性.

The structure of double closed-loop DC motor control system was studied.According to the system structure,the current regulator and the speed regulator were designed in accordance with the order from the inside to the outside.To make the system has no static error,PI regulator was chosen.In the course of the simulation based on Simulink,the controller parameters were tuned to make the system steady.The rationality of the design was shown through the simulation curve.
