摘要
为了改善移动卫星天线的控制性能和稳定性,本文进行移动卫星天线的自适应鲁棒控制系统的研究．首先针对移动卫星天线数学模型,设计自适应鲁棒控制器和控制系统,所提出的自适应鲁棒控制律和控制系统不仅保证了闭环系统的稳定性,而且实现了所期望的性能,最后通过试验结果证明该控制算法的有效性,尽管外界环境道路条件的变化不同,移动卫星天线控制系统表现了满意的控制性能．
The use of the adaptive robust controller for improving control performance and stability of mobile satellite antenna systems is investigated in this paper. An adaptive robust control system of mobile satellite antennas is presented. The adaptive robust controller is designed according to the mobile satellite antenna systems model. The proposed adaptive controller and the corresponding robust adaptive law not only keep the closed-loop system robustly stable, but also provide the expected performance. Finally, the effectiveness of the algorithm is verified by experimental results, demonstrating that the control performance and stability of mobile satellite antenna systems are improved, and the control system maintains satisfactory control performance despite the change of road surface condition.
