摘　　要：结合防空导弹的精确末制导问题,根据红外成像制导的特点,应用平行接近原则、最优控制理论和滑模变结构控制理论,设计了一种准最优变结构制导律。通过对比分析,这种制导律弹道特性良好,且在制导过程中不需要知道目标精确的加速度和速度方位信息,适合于红外成像制导防空导弹使用。In order to solve the problem of the precision guidance of the air defense missile of the infrared imaging guid- ance, the sub-optimal variable structure guidance law, is deduced, which is based on the theory of the optimal control, sliding-mode variable structure control and parallel approach. Through the comparative test, the simulations show the excellent performance of the guidance law. During the missile guidance, we needn＇t know the precision the acceleration and velocity of the target, so the guidance law can be used in the infrared imaging missile.
