摘要
磁悬浮系统在实际运行中会出现模型摄动和各种外界干扰,提高磁悬浮系统的鲁棒性非常重要,给出了磁悬浮系统的数学模型;结合H∞控制和滑模控制的优点,给出一种H$控制和滑模控制的融合算法,把该算法应用在磁悬浮系统中;通过Matlab仿真,验证了该算法能有效抑制磁悬浮系统中存在的确定性和不确定性干扰,从而使控制系统的性能得到提高。
Magnetic levitation control system has model perturbation and a variety of outside interference during operation, so, improving the robustness of magnetic levitation system is very important. This paper gives a mathematical model of magnetic levitation system;a fusion algorithm of H∞ and sliding-mode control is discussed;simulation is obtained by Matlab tool. The results show that the algorithm is robust to the uncertainty of the system on the matching and non-matching at the same time.
