变转速泵控马达系统位置控制试验研究

摘要

对变转速泵控马达调速系统存在的位置跟踪效果不理想问题进行了研究，并针对马达角位移控制提出了闭环PID控制方法。基于虚拟仪器技术完成了位置控制测控系统的开发，将开发出的测控系统应用到变转速泵控马达调速系统上，完成了马达角位移的开环控制、闭环PID控制试验。试验结果表明，采用闭环PID控制时的马达角位移跟踪效果明显好于开环时的跟踪效果。%The problem of bad position tracking effect in governing system of variable-speed pump-control-motor was studied. And the closed-loop Proportional-Integration-Differential (PID)control method was proposed by aiming at the motor angular displace-ment control. The measurement and control system of position control based on virtual instrument technology (Labview)was devel-oped. The measurement and control system was applied to the governing system of variable-speed pump-control-motor. Then the related experiments of motor angular displacement control were carried out under open-loop control and closed-loop PID control. The result of experiments shows that the effect of closed-loop PID control of motor angular displacement is significantly better than that of open-loop control.
