摘要

Radar leveling system is the key equipment for improving radar mobility and survival capability. Simulations were carried out to study synchronization capability of hydraulic lift system of radar antenna truck by using MATLAB and Simulink. To eliminate the influence of the manufacturing errors of cylinders and load disturbance on the synchronization control precision,the QFT (quantitative feedback theory)leveling controller was put forward. Simulation results demonstrate the designed controller has high synchronization accuracy and fast dynamic response as well as stability. The leveling controller can drive the radar truck leveling platform accurately,quickly and stably.%　　雷达天线车自动调平系统是雷达的一个重要组成部分，对提高雷达的测量性能和机动能力起着决定性作用。为了解雷达车电液升降系统的同步协调特性，采用MATLAB和Simulink软件建立了系统调平模型并进行了仿真研究。为消除电液调平系统液压缸参数制造误差、各通道负载不均衡等对同步控制精度的影响，设计了定量反馈控制（ QFT）同步调平控制器来提高倾角调平精度。仿真结果表明：设计的调平控制器具有良好的同步精度和快捷的响应速度，能驱动调平仿真台快速、稳定地运动。
