摘要:
?针对载机机动运动导致雷达伺服机构中存在复杂的耦合扰动力矩,无法实现伺服控制中扰 动力矩精确补偿的问题,展开雷达伺服系统耦合力矩的建模和影响分析。采用矢量叠加原理推导 两维机构的运动学方程和惯量耦合方程,建立方位和俯仰两轴的动力学耦合力矩模型,并通过仿真 分析载机机动和不机动情况下,载机平台对两维框架的动力学耦合力矩和位置跟踪误差的影响。 仿真结果表明,载机不机动时两维框架间的耦合力矩较小,跟踪误差较小; 当载机机动时两维框架 间耦合力矩增大,且耦合力矩表现为时变的正弦特性,此时跟踪误差增大且表现为时变和不规则的 特点。动力学耦合力矩模型的建立为机载雷达伺服控制系统的设计提供了理论依据。
Abstract:
For airborne radar servo system, the disturbance torque is relatively complicated due to its strong maneuverability. To explore the subject on the accuracy compensation of the disturbance torque, the couplingtorque model of the system and the related influence were researched. The superposition theorem was adopted to deduce kinematics equation and inertia coupling equation of the 2D frame, and to develop dynamic couplingtorque model in the azimuth-axis and elevation-axis. Furthermore, the influence of the airborne platform on the dynamical couplingtorque and positiontracking error of 2D frame in the case of maneuvering or not, was analyzed by means of simulation. The calculated result shows that the coupling torque and target tracking error are relatively small when airplane is not maneuvering. On the contrary, when airplane is maneuvering, the coupling torque between 2D frames increases significantly and presents sinusoidal characteristics, while the targettracking error also becomes time-varying and irregular. The dynamic couplingtorque model studied provides the theory foundation for the design of the airborne radar servo system.
