47828 最后,讨论了反推滑模变结构控制目前存在的问题及其可能的解决途径。 Finally, discussed the present problems of the backstepping sliding mode variable structure control and their possible solutions.
47829 针对一类含不可控不稳定线性化的高阶非线性系统的跟踪控制问题,给出了一种连续状态反馈动态面控制器设计方案。 For a class with uncontrollable unstable linearization of higher order tracking control problem of nonlinear systems, a continuous state feedback is given a dynamic surface controller design scheme.
47830 基于增加幂次积分方法,利用状态参考的思想,设计了可导的期望虚拟控制律。利用动态面技术,让期望虚拟控制律的函数通过一阶低通滤波器,避免了对期望虚拟控制律的函数进行微分。 Increased based on the exponential integral method, using the ideas of state reference, can guide the expectations of the virtual control law is designed, by using dynamic surface according to the function of virtual control law by first-order low-pass filter, avoid the expected function of the virtual control law for differential.
47831 所提连续状态反馈动态面控制器能够保证跟踪误差半全局一致终结有界。 The proposed dynamic surface continuous state feedback controller can guarantee the global asymptotical end half tracing error to be bounded.
