| Abstract: | According to the relative motion equation of space platform interceptor and target,an optimal integrate-control laws of 3D minimal miss distance and the minimal energy was put forward based on linear optimal control theory in this paper.The models of the value and direction control for optimal thrust,and the optimal transition time and turn-off time of optimal control method were established. The simulation results showed that this optimal control law had high control accuracy and was easy to apply in engineering. |
