The servo loops include speed control loop and position control loop plus feed-forward control, therefore the system is a compound control system.

该伺服系统包括速度环和位置环以及前馈控制，因此该系统是一个复合控制系统。

Experimental results show that the system performance using the proposed control strategy is better than that using the control strategy with position control loop only.

实验结果表明：与仅有位置控制环的控制策略相比，该方法提高了系统的稳态精度和动态性能。
