在航路捷径附近,靶场单脉冲测量雷达的伺服控制器使用传统PID(比例积分微分)角误差控制方法跟踪飞行目标时,会产生较大的动态滞后误差。针对这种情况,提出采用带状态观测的增广状态反馈控制方法,通过实时观测系统内部状态信息(状态变量)并及时根据状态进行系统调节的控制方式,可以实现对高速目标的快速稳定跟踪。经过仿真和系统试验,证明这种控制方法可以较大地提高系统的动态响应速度并减小航路捷径附近的动态滞后误差。
In the vicinity of the route shortcuts, the servo controller of the single pulse measurement radar rangefinder has a large dynamic hysteresis error when tracking the flight target using the traditional PID (proportional integral derivative) angle error control method. In view of this situation, an augmented state feedback control method with state observer is proposed. By observing the internal state information (state variables) in real time and timely adjusting the system according to the state, fast and stable tracking of high-speed targets can be achieved. After simulation and system test, it is proved that this control method can greatly improve the dynamic response speed of the system and reduce the dynamic hysteresis error near the route shortcuts.
