| 摘 要： | 摩擦非线性造成机载光电跟踪平台伺服系统低速不平稳性,增加了系统的稳态误差.常规PID控制难以满足光电跟踪平台高精度伺服系统的性能要求.采用一种新的二阶离散系统最速控制函数设计自抗扰控制器,将它作为机载光电跟踪平台伺服系统的位置环控制器.实验结果表明,当系统跟踪幅值为0.5°、频率为0.159 Hz的正弦输入信号时,在0...

| Abstract: | The friction nonlinearity in the servo system of an air-borne opto-electronic tracking platform causes creeping phenomena in the lower velocity and increases the steady error of the servo system.It is difficult for the routine PID controller to satisfy performance specifications of the high precision servo system of the opto-electronic tracking platform.An Active Disturbance Rejection Controller(ADRC) with a new control function of the second-order discrete system is studied.The new ADRC is used as the posi... |
