摘　　要：为了提高输灰系统杆驱机构双缸同步控制精度,设计了一种推进过程模糊比例-积分-微分(PID)控制方案,采用闭环同步控制。构建了模糊PID控制器,并通过Simulink完成仿真测试,验证了推进过程的同步控制性能。研究结果表明:速度信号发生了先加速,之后进入稳定速度,最后再减速。低速下,以模糊PID控制的双缸最大同步误差为0.085 mm,在稳定状态下的误差为0.002 2 mm;高速下,以模糊PID控制的双缸最大同步误差降低至0.13 mm,在稳定状态下的误差减小为0.03 mm。无论是高速还是低速,模糊PID控制相对于传统PID控制方式表现出更低的双缸同步误差,可以获得更高的系统控制精度。In order to improve the double cylinder synchronous control accuracy of the rod drive mechanism of ash transport system,a fuzzy PID control scheme is designed,which adopts closed-loop synchronous control.The fuzzy PID controller is constructed,and the simulation test is completed by Simulink to verify the synchronous control performance of the propulsion process.The results show that the speed signal first accelerates,then enters the stable speed,and finally decelerates.The maximum synchronization error of the two cylinders controlled by fuzzy PID is only 0.085 mm at low speed,and 0.0022 mm at steady state.At high speed,the maximum synchronization error of the two cylinders controlled by fuzzy PID is reduced to 0.13 mm,and the error is reduced to 0.03 mm under steady state.Compared with the traditional PID control mode,fuzzy PID has lower two-cylinder synchronization error and can obtain higher system control accuracy.
