Approximate Time Optimal Control Method for Radar Search and Tracking Conversion

为解决时间最优控制(time optimal control,TOC)存在的颤抖和鲁棒性下降问题,提出一种雷达搜跟转换近似时间最优控制(proximateTOC,PTOC)方法。以搜跟雷达方位伺服作为研究对象,在电机角速度和角加速度受约束的条件下,设计近似时间最优控制器,建立控制数学模型,并基于Matlab进行仿真论证及实物验证。验证结果表明:该算法切实可行,能达到系统技术指标要求,可广泛应用于搜跟一体雷达伺服系统中。

In order to solve the problems of chattering and robustness degradation in time optimal control(TOC),an proximate time optimal control(TOC)method for radar tracking conversion is proposed.Taking the azimuth servo of tracking radar as the research object,the approximate time-optimal controller is designed under the constraint of motor angular velocity and angular acceleration,and the control mathematical model is established,and the simulation demonstration and physical verification are carried out based on Matlab.The results show that the algorithm is feasible and meets the technical requirements of the system,which can be widely used in the search and tracking radar servo system.
