摘要
针对工程实际中,制导炮弹的舵翼尺寸一般较小,可用过载较小,受重力影响较大,导引律参数选取较为繁琐的现状,推导出一类过重力补偿比例导引律的形式,并证明其需用过载的取值范围的可确定性;摒弃了前人采用经验尝试选取导引律参数的方法,将导引律参数选取问题,转化为一类最优化问题,并使用杂交粒子群算法进行了求解。利用优化设计所得到的导引律与计及重力补偿的导引律,进行了六自由度全弹道仿真,并对比分析。仿真结果表明,其过载显著降低,在有效增加弹着角的情况下,能准确命中目标。
Being interested in the guidance law design of guided projectile stems from its several existing problems in practice,such as the small available overload limited by the rudder sizes,great influences from gravity and the complex parameter selection,a proportional gravity compensation guidance law was derived to assure the required overload within a determined range. Instead of the traditional empirical method to select various parameters,an optimization problem was introduced and solved by using hybrid particle swarm algorithm. To verify the feasibility of the proposed proportional navigation guidance law with gravity over compensation,a six degree of freedom trajectory simulation was carried out,and a comparative analysis follows. The simulation results show that an accurate hit can be achieved by increasing the impact angle to a certain degree,with a significantly reduced overload.
