| 摘 要： | 提出一种液压伺服系统自适应模型跟踪模糊变结构控制的设计方法，控制量由等效控制分量和切换控制分量所组成。依据理想的滑模特性确定等效分量，当被控系统存在参数和外干扰不确定的情况下，根据李亚普诺夫稳定法所求出的切换分量能使其状态到达滑模面并实现滑模运动，使系统的跟踪误差大范围渐近收敛。采用模糊控制方法使系统在滑模状态下的颤振得到缓减。仿真表明，该控制方法能得到较满意的结果。

| Abstract: | The design of adaptive model-following control was presented based on sliding mode control (SMC) and fuzzy logical control (FLC) for hydraulic servosystems.For the system the control law consists of equivalent control and switching control,the equivalent control is determined by the sliding-mode equation and the switching control is added to guarantee that the state reaches the sliding mode in the presence of parameter and disturbance uncertainties.Fuzzy turning schemes were employed to reduce chattering.The Lyapunov stability method was used to guarantee the asymptotic convergence of the control strategies.The simulation results demonstrate the satisfactory results. |
