摘要
针对采用脉冲矢量控制发动机作为控制执行机构的导弹,提出一种基于状态预测的脉冲控制算法.给出了算法的基本思路;由导弹短周期扰动运动方程组出发构造了预测模型;考虑过载指令跟踪精度及脉冲发动机能量消耗,构造了代价函数.算例设计及仿真结果表明,采用所提出的方法设计的脉冲控制算法能够保证导弹对制导回路过载指令的可靠跟踪,同时,还能够有效抑制脉冲发动机的能量消耗.
A pulse control algorithm based on state prediction is proposed for the missile with pulse motor as control actuator.Systematic description of the algorithm was given.Prediction model was constructed by using short-period disturbance motion equations of the missile.Cost function was established with the consideration of the overload tracking accuracy and energy consumption of the pulse motor simultaneously.Design examples and simulation results show that the pulse control algorithm designed by proposed method could ensure that the missile overload tracks the overload command given from guidance loop reliably.Also,the pulse control algorithm could lower the energy consumption of pulse motor effectively.
