摘要
为了提高雷达系统的性能,要求雷达天线伺服控制系统稳定性高、动态特性好、稳态误差小以及鲁棒性强。针对如上需求,提出了一种自适应离散控制方案,它由位置反馈控制器、自适应零相差前馈控制器(ZPETC)和自适应零相差滤波器(ZPEF)组成。计算机仿真结果表明,所提出的控制方案可实现雷达天线快速、精确的跟踪,而且具备针对参数摄动的较强适应性。
In order to improve the performance of radar system,the radar antenna servo control system is required by high stability,good dynamic characteristic,small steady-state error and strong robustness.In response to the above needs,a adaptive discrete control scheme is proposed.Moreover,the proposed scheme is composed by a position feedback controller,a adaptive zero phase error tracking controller(ZPETC)and a adaptive zero phase error filter(ZPEF).The computer simulation results present that,the proposed control scheme can achieve fast and accurate tracking of radar antenna, and also possess stronger adaptability with parameters variations.
