摘　　要：设计一种基于变频调速的液压闭式回路,通过PLC控制变频器达到控制整个液压系统的目的。对闭式回路分别采用传统PID控制算法与PDF控制算法,建立Lab VIEW界面观测系统的响应特性。实验结果证明:引入伪微分反馈控制算法能改善执行机构的响应特性,鲁棒性更强。A kind of closed hydraulic loop based on variable frequency speed regulation was designed,through PLC control the inverter to control the hydraulic system. The traditional PID control and the pseudo derivative feedback control were used for the system. Lab VIEW interface was built to observe the response. The results show that using the pseudo derivative feedback control can improve dynamic characteristics and robustness.
