【 摘 要 】

Design problem of a H∞ robust lower order controller of an AC servo system of multiple rockets is studied. It is pointed out that the problem is actually H∞ robust performance design problem, H∞ robust stability and performance requirements (enhance rapidity, shorten overshoot and static error). It is also recommended to represent the robust performance design as H∞ robust control problem and solve H∞ low-order controller, if the uncertainty weighting function and performance weighting function of system bandwidth and interference attenuation are properly modified. Solved the H∞ low-order controller. The simulation results show that the robust H∞ lower order control system has advantages of small overshoot and short setup time. It can also improve control system's anti-disturbance ability. The simulation example of the H∞ lower order control is also provided to demonstrate the effectively of the proposed design method. The H∞ lower order controller is easy for engineering implementation.
