Control of attitude of the space interceptor based decision tree

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 strategy 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.
