针对反导拦截过程中拦截时间短时传统比例导引制导脱靶量大的问题,运用滑动模态变结构控制理论,提出了快速趋近滑模制导律及高精度制导信息快速提取算法,在典型交战条件下与比例导引、扩展比例导引及开关偏置比例导引方法进行了仿真对比,结果表明该制导律实现了滑模趋近的快速性,有效抑制了指令的发散,滤波算法能快速有效提取有色噪声条件下制导信息,大大提高了制导精度,为高精度反导拦截打下了基础.
Aiming at the large miss distance of traditional proportional guidance guidance system with short interception time during the course of anti-missile interception, this paper proposes a fast approach sliding mode guidance law and a high-precision guidance information rapid extraction algorithm using sliding mode variable structure control theory. The simulation results show that the guidance law achieves the fastness of the sliding mode approach and effectively restrains the divergence of the instructions. The algorithm of filtering algorithm Fast and effective extraction of guidance information under the condition of colored noise greatly improves the guidance accuracy and lays the foundation for high-precision anti-missile interception.
