摘要:研究了一种适用于军事隐蔽式侦察的小型漂浮式卫星天线双环自抗扰控制器,实现了在中小涌浪扰动下天线自动跟踪目标卫星的俯仰伺服控制.以自抗扰理论为基础,结合小型天线俯仰控制的特点分别设计了位置环和速度环自抗扰控制器;比较了双环自抗扰控制器和比例-积分-微分(Proportional-Integral-Derivative,PID)控制器的阶跃响应,验证了双环自抗扰控制器性能优于PID控制器性能;利用半实物仿真平台,以中小涌浪扰动下天线系统俯仰角的变化为控制器的输入,进行天线俯仰伺服控制,通过检测到的信标信号验证了双环自抗扰控制器可以实现中小涌浪扰动下天线对目标卫星的稳定跟踪.
A double loop active disturbance rejection controller for small float antenna applied in military hidden reconnaissance is presented.Active disturbance rejection controllers of position loop and velocity loop of the elevation servo control system are designed.The performance of the double loop active disturbance rejection controller is better than the proportional-integral-derivative(PID)controller by comparison of the step response.The elevation variation of the antenna under the disturbance of medium and small surge is input to the double loop controller to control the antenna elevation servo system by hardware in the loop simulation.Experiments validate the presented double loop active disturbance rejection controller can ensure the antenna system to well track the target satellite.
