随动系统是一种反馈式闭环控制系统,用角度反馈信号去控制角位移.随动系统自控装置在稳态精度很高的情况下,可以准确实现飞机、船舶的导航,机加工设备的自动化.在国防、工业上都有很高的实用价值.如何减小系统的稳态误差,提高系统的稳态精度,很值得研究.在古典的自动控制中,随动系统一般依照图1的原理实现角度跟踪.在图1所示的传统控制系统涉及 The servo system is a kind of feedback closed-loop control system, which uses the angle feedback signal to control the angular displacement.The servo system of the servo system can accurately realize the navigation and machining automation of the aircraft and ships under the condition of high steady-state accuracy In the national defense, industry has a high practical value.How to reduce the system steady-state error, improve the steady-state accuracy of the system, it is worth studying .In the classical automatic control, the servo system in accordance with the principle of Figure 1 Achieve angle tracking. The traditional control system shown in Figure 1 is involved
