Research on intelligent control of mechatronics equipment based on improved PID

目前设备控制方法难以达到期望的控制效果,为了提高设备可靠性,对基于改进PID的机电一体化设备智能控制方法进行了研究。首先,对机电一体化设备进行状态监测,采集机电一体化设备的实时参数;然后,通过均分各台运行设备的负荷率,控制设备效率,协同调度设备间工作任务,区分设备任务的优先级;最后,基于改进PID智能控制机电一体化设备,通过调节PID参数,实现智能控制。实验证明,与基于常规PID的控制方法和基于模糊PID的控制方法相比,所提方法控制下的电机稳定性更强,能够有效降低振动的幅值,从而提高工件的表面质量;且电机d轴电流曲线的振动较小,具备更优越的动态性能和静态性能。

At present,the equipment control method is difficult to achieve the desired control effect.In order to improve the reliability of the equipment,an intelligent control method for electromechanical equipment based on improved PID is proposed.It collects real-time parameter data of equipment through electromechanical integration equipment status monitoring,sets the minimum energy consumption conditions after load distribution and efficiency optimization,evenly divides the load rate of each operating equipment,and controls the equipment efficiency;cooperates to schedule work tasks among devices,and distinguishes the priority of equipment tasks.Based on the improved PID intelligent control electromechanical equipment,it adjusts the PID parameters to achieve the goal of intelligent control.Compared with the control method based on conventional PID and the control method based on fuzzy PID,the stability of the motor controlled by this method is stronger,which can effectively weaken the amplitude of vibration and improve the surface quality of the workpiece,the d-axis current curve of the motor has less vibration and better dynamic and static performance.
