摘要

In order to solve the multi-DC motors' synchronization control in field of process automation, with DC-motor synchronization control as the research object, the mathematical model of the control system was established from the parameters of the DC-Motor, the synchronization control system based on the traditional PID control method and ils corresponding problems were analyzed. Then a fuzzy-PID controller was designed through the combination of fuzzy and PID control. Numerical simulation results show the good robustness,fast response and negligible error in the system, which can greatly suffice for the requirement of high precision of the system. And the developed experimental platform for this system is also verified with qualified results.%为了更好地解决过程自动化领域多电机同步控制问题,以直流电机同步控制为研究对象,根据直流电机参数建立了控制系统数学模型,分析了采用传统PID方式控制电机同步系统而存在的问题,将模糊控制与传统PID控制相结合,设计出了模糊PID控制器.数值仿真及实验结果表明,该方案鲁棒性优良,响应快速,动态过程中同步误差小,能够较好地满足被控对象对高精度同步控制的要求.所开发的模糊PID控制软硬件系统在相应的实验平台上获得了较好的控制效果.
