随动系统主要用于跟踪空中飞行目标,目标的方位可以由水平方位角和高低角度确定,由于水平角和高低角随时间变化的函数往往很复杂,在求控制系统的稳态误差时,难以对目标输入函数进行拉普拉斯变换;采用一种用曲线来拟合逼近目标函数的方法,达到了很好的效果;进而根据系统精度要求可以确定控制系统的放大增益。通过对随动系统的控制和分析,建立控制系统的数学模型,得到随动系统跟随目标函数的响应曲线;随动系统要求有很好的稳定性和很高的精度,采用了一种滞后-引前的校正方法,用MATLAB仿真模拟,并进行时域和频域的综合分析,得到了理想的仿真结果。
Follow-up system is mainly used to track the flight target, the target position can be determined by the horizontal azimuth and elevation angle, as the horizontal angle and height angle with the time-varying functions are often complex, in the control system for the steady-state error, it is difficult Laplacian transformation is applied to the target input function. A curve fitting method for approximating the objective function is used to achieve good results. Then, the amplification gain of the control system can be determined according to the system accuracy requirements. Through the control and analysis of the servo system, the mathematical model of the control system is established, and the response curve of the servo system following the objective function is obtained. The servo system requires good stability and high precision, and adopts a lag- The lead calibration method, using MATLAB simulation, and comprehensive analysis of the time domain and frequency domain, the ideal simulation results.
