In order to solve the problem of controllability of space-intensive modal structures with poor controllability, an optimal control scheme is proposed, which can optimize the amplitudes of the poorly controllable modes while the pole of the system is properly configured. Ability to adapt to the initial state of uncertainty, a model reference adaptive mechanism is also proposed to track the amplitude optimal control online, and the stability of the adaptive control system is proved.The simulation results show that the proposed control The effectiveness of the method
