针对直流调速系统PID参数经典设计方法中要处理非典型系统,不能实现实时调整参数等问题,本文提出了一种动态参数设计方法.该方法基于经典双闭环直流调速系统动态结构,通过建立系统动态仿真模型,动态设计PID参数和调整系统性能指标,以获得满足设计要求的结果.仿真实例应用表明:动态参数设计可快速准确地实现系统设计要求,是直流调速系统PID参数设计的一种有效方法.

In conventional design of PID parameters in DC speed regulating system,it needs to deal with atypical system to typification and can not achieve real-time adjustment of PID parameters;thus a dynamic design method is introduced.The method based on the double closed loop DC speed regulating system has established a dynamic system simulation model;dynamic design of PID parameters and adjusting system performance are realized in order to meet the design requirements.The simulation results demonstrate that the method of dynamic design can satisfy the design requirements quickly and accurately;and it is effective in PID parameter design of DC speed regulating system.
