摘　　要：为提高雷达天线车机动性、缩短其架撤和调整时间,为雷达天线提供高精度水平工作平台,针对某军用雷达车设计了一种高精度自动调平控制系统。建立了系统的数学模型,分析影响调平支腿输出位移的主要因素。对当前调平策略进行分析比较,选用追逐最高支撑点调平策略,在传统PID控制基础上引入积分分离式PID控制的方法。控制系统采用HAWE公司阀用可编程控制器PLVC为控制核心,开发了4点电液调平系统。试验结果表明:该调平系统性能优异,调平控制策略具有较好的控制性能,调平精度达到2.5′,自动调平时间不超过30s。In order to improve the maneuverability of the radar vehicle,shorten its time of erection,withdrawal and adjustment,provide a high precision horizontal working platform for the radar antenna,and design a high precision automatic leveling control system for the military radar vehicle.In order to analyze the main factors that affect the output displacement of the leveling legs,the mathematical model of the system is established.Based on the analysis and comparison of the current leveling strategy,select the pursuit of the highest support point leveling strategy,based on traditional PID control introduced the integral-separation PID control method.The control system uses HAWE valve with programmable controller PLVC as the control core,developed four-point electro-hydraulic leveling system.The experimental results show that the leveling system has excellent performance and the leveling control strategy has better control performance.The leveling accuracy is 2.5′and the auto leveling time is less than 30s.
