研究可控性差的空间密集模态结构的控制问题 ,提出了一种最优控制方案 ,在适当配置系统极点的同时 ,优化可控性差的模态的振幅 .目标函数的寻优采用具有全局搜索能力的遗传算法 .为适应不确知的初始状态 ,也提出一种模型参考自适应机制 ,用来在线跟踪振幅最优控制 ,自适应控制系统的稳定性得到证明 .仿真结果表明了所提出控制方法的有效性 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
