摘　　要：为解决由于迟滞、液压、结构等因素导致的压电式数控点胶机点胶轨迹难以精确控制以及提高点胶机速度等问题,提出一种基于模糊PID控制的数控点胶机轨迹跟踪方法。通过对点胶系统的分析和建模,并运用模糊PID控制器对其进行补偿控制。结果表明,使用这种控制器对压电式数控点胶机的点胶轨迹具有较好的控制效果,且该方法可用于其他类似数控点胶系统,具备通用性。The trajectories of the piezoelectric dispensing machine are usually difficult to precisely control dueto the factors of hysteresis, hydraulic pressure, structural nonlinearity. In order to improve the speed and accuracyof dispensing system, a method of trajectory tracking is proposed based on the fuzzy PID control for piezoelectricdispensing machine. By analyzing and modeling the dispensing machine, the fuzzy PID controller is usedto compensate the errors. It is shown that this kind of controller is suitable for the trajectory tracking of piezoelectricdispensing machine and has excellent control effect. This kind of method can be applied to other similarNC dispensing system,and have the versatility.
