增广状态反馈在雷达伺服控制系统中的设计实现

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。

Design and Implementation of Augmented State Observation in Radar Servo Control Systems

An augmented state-feedback control method using state observation is proposed to reduce dynamic lag errors of the servo control system of a monopulse radar when the traditional PID(Proportional Integral Differential) angular control method is used to track a flying object close to the approaching point in range experiment.Fast and stable tracking of high-speed objects is made possible through a control approach that observes system internal state information in real-time and makes adjustments in a timely manner.Simulation and system verification shows that the control method significantly increases dynamic response speed and reduces the dynamic lag error close to the approaching point.
