【摘要】 本文针对应用经典控制进行弹道导弹姿态控制系统设计时,面临的环境建模困难和控制器调参在一定程度上的盲目性等问题,提出一种将自适应技术中的系统参数辨识估计方法和模型参考自适应控制中的Narendra控制方法结合的新方案,并应用于设定的被控对象中,通过数字仿真验证,设计过程简单易行。同时被控对象能够在稳定和具备一定鲁棒性的基础上,跟踪理想输出效果良好,并且跟踪速度满足执行机构的动作速度,说明该方法在弹道导弹控制系统设计中具备可行性。更多还原

【Abstract】 Due to the difficulties in classical method of ballistic-missile attitude control system designing such as complexity of environment modeling & blindness of controller parameter regulation, this paper present a new method which combine the advantages of Narendra Model Reference Adaptive Control Method & System Parameter Estimate Method. Then it was apply to a given plant by numerical simulation which is easy and convenient. The result showed that the plant could track ideal output very well while the controller still has enough robust stability. Besides the tracking speed can satisfy the response speed of actuator well, which indicates that the method is reliable and feasible.更多还原
