| 摘 要： | 针对当代大型天文望远镜驱动伺服系统中存在的非线性干扰,分析了非线性干扰的类型。在此基础上建立了大型望远镜驱动控制系统的数学模型,提出了高阶滑模控制方案,将系统中存在的不连续性拓展到状态控制的最高阶,抑制系统的高频振动现象,克服了普通滑模控制的缺点数值仿真证明了该方案的可行性和有效性。

| Abstract: | In order to solve the general problem of nonlinear disturbance in large astronomical telescope servo- control system,the types of disturbance were analyzed in this paper.Based on it,an integrated mathematical model of large astronomical telescope servo-control system was made and a new control strategy based on higher-order sliding mode control was proposed.The discussions were then expanded to the discontinuity in control system to highest- order of state control.This strategy could overcome high frequency vibration of common sliding mode control.The simulation results were well demonstrations to the feasibility and effectiveness of presented control strategy. |
