摘　　要：针对传统模型预测静态规划(MPSP)算法在解算过程中涉及矩阵求逆,易出现矩阵奇异、数值稳定性较差问题,提出一种标量MPSP算法。在传统MPSP型末制导律的基础上,基于标量终端约束提出一种标量MPSP型末制导律,并针对导弹打击地面静止目标的场景进行仿真分析。仿真结果表明,相比于传统MPSP型末制导律,标量MPSP型末制导律对于初始猜想的敏感度更低,数值稳定性更高。For the problem of the traditional model predictive static programming(MPSP)algorithm involves matrix inversion during the solving process,which is prone to matrix singularity and poor numerical stability,a scalar MPSP algorithm is presented.On the basis of the traditional MPSP method,a guidance law based on the scalar MPSP method was designed.The flight scenes that the missile attacks against stationary target were simulated.Simulation results show that the scalar MPSP guidance law has lower sensitivity to initial guess and represents higher numerical stability,in com-parison with the traditional MPSP terminal guidance law.
