报告摘要：

The popularity of digital computers in industrial automation systems has made the research of nonlinear sampled-data control systems become a hot topic in the field of control theory. In this talk, we focus on the design problem of nonlinear sampled-data systems. Based on the Lie series representations of solutions of ordinary differential equations and the idea of Lyapunov-based redesign, a multi-rate sampled-data controller with the form of the power series expansion is proposed to achieve the global asymptotic stabilization for a class of high-order nonlinear systems. Approximate solutions of the proposed controller are proved to be effective in the practical implementation. The results show that, compared with the emulated control scheme, our controller allows considering larger sampling periods and enlarges the domain of attraction for a given sampling period.
