摘要: 拦截器的发动机为带脉冲型发动机,从而限定了作动器的输出集.对于该拦截器的姿态控制,提出了基于决策树的控制方法.它是通过搜索决策树代价最小的路径做出控制决策,该控制思想非常类似棋手博弈的思想.提出的剪枝方案降低了决策树的计算复杂度.通过仿真实验说明:基于决策树的控制具有一定的智能;不同剪枝方案产生不同的控制效果;该方法较好地解决了输入受到约束、非线性和耦合的多输入多输出控制问题,并且在满足控制精度前提下可减少发动机切换次数和燃料消耗.Abstract: The idea of control based decision tree was proposed for attitude control of the space interceptor with the on-off actuators. Control decision was made every time by searching the decision tree for the path of minimum cost .The idea is quite similar to that of playing chess. The proposed pruning stragey reduced computational complexity of the decision tree. The simulation results suggest that the control based decision tree is intelligent and different pruning strategies bring different results. The simulation results also suggest that this method preferably solves the multiple input multiple output (MIMO) control problem of nonlinear and coupling system which subjects to restricted control input. This method also reduces the switch count and the consumed fuel of the engine under the precondition of meeting the control accuracy.
