建立了基于移动卫星天线的控制系统，并针对移动卫星天线模型，设计μ鲁棒控制器，试验结果证 明了控制器有效性；尽管外界环境道路变化不同，移动卫星天线控制系统表现出满意的控制性能。

This paper investigates the use of the μ robust controller for improving control performance of mobile satellite antennas. A robust control system of mobile satellite antennas is presented,  and the μ robust controller is designed according to the mobile satellite antennas systems model.  The effectiveness of the algorithm is verified by the experimental results.  It is clarified that the control performance of mobile satellite antennas is improved and the control system still maintains satisfactory control performance despite the change of road surface condition.
