摘要
为设计某试验台转速负反馈闭环直流调速系统,建立闭环调速系统动态数学模型,并计算出转速负反馈闭环调速系统基本参数。使用Simulink模块对系统进行仿真。由于原系统不稳定,通过设计PID控制器对系统进行校正,仿真结果表明校正后系统具有较好的响应速度和快速稳定性能,达到了系统改进要求。
In order to design direct current timing system with speed negative feedback for testrig,the mathematical models has been built.The calculation is done for system basic parameters.The correction is done to the original unstable system using PID controller.The simulation conclude the compensated system has a rapid reaction speed and stability.So,the PID correction meets the design requirements.
