预见PID控制在液压挖掘机控制中的应用

Application of Preview PID Control Technology to Hydraulic Excavator

对预见PID控制进行了分析,给出了相应算法,并应用于液压挖掘机工作装置的轨迹控制过程中,试验结果表明,控制算法可行,控制效果优于未引进预见信息的PID控制。

A PID control technology based on preview is presented. The method is used to improve the control of hydraulic excavator attachment. The experiment results show that preview PID control is more reasonable and effective than PID control when preview information in the working process can be used.
