针对一类非线性系统,提出了一种基于模糊小脑关联结构模型(CMAC)神经网络的多面滑模变结构控制算法,其特点是无需已知不确定性函数及其各阶导数的上界,并且允许控制矩阵存在不确定性。用Lyapunov稳定性定理证明了系统的状态及权值误差... 针对一类非线性系统,提出了一种基于模糊小脑关联结构模型(CMAC)神经网络的多面滑模变结构控制算法,其特点是无需已知不确定性函数及其各阶导数的上界,并且允许控制矩阵存在不确定性。用Lyapunov稳定性定理证明了系统的状态及权值误差最终一致有界。与经典设计方法相比,所提出的方案允许非参数化不确定性。仿真实例显示了方法的有效性。 展开更多

A global fast convergent integrated guidance and control design approach is proposed. A disturbance observer is utilized to estimate the uncertainties of integrated guidance and control model in finite time. According to the multiple sliding-mode surface control, the independent nonsingular terminal sliding functions are presented in each step, and all the sliding-mode surfaces run parallel. These presented sliding-mode surfaces keep zero value from a certain time, and the system states converge quickly in sliding phase. Therefore, the system response speed is increased. The proposed method offers the global convergent time analytically, which is useful to optimize the transient performance of system. Simulation results are used to verify the proposed method. 展开更多
