摘要
在跟踪控制系统中,速度回路控制对象的特性对控制系统的跟踪精度有很大的影响。根据电流负反馈的基本原理,在位置、速度双闭环的基础上加入了电流反馈传感器,设计了电流环校正网络。仿真和实验表明,电流环有效地改善了速度回路控制对象的特性,提高了速度回路的低频增益,控制系统位置回路的跟踪精度约有 10 倍的提高。
In a tracking and control system, the tracking accuracy of the control system mainly depends on the features of the object in the velocity loop. According to the basic principle of current negative feedback and through adding some current feedback sensors on the basis of position and velocity dual-loop, a current loop is designed. The simulation and experiment results show that the control object character is effectively improved and the low-frequency gain of the velocity loop is raised by the current loop. The tracking accuracy of the position loop in the control system is enhanced by about 10 times.
