针对一类非线性系统,提出模糊混合H_2/H_∞采样控制方案.应用T-S模糊系统表征非线性系统,控制器是零阶保持采样信号.采用输入时延方法,闭环系统转换成连续时延系统.应用Lyapunov-Krasovskii函数和LeibnizNewton公式,由线性矩阵不等式给出模糊采样控制器存在的一个新充分性条件.所提出的模糊采样控制方案在确保系统稳定意义下取得了期望的H_2/H_∞性能.通过卡车拖车系统实验验证了采样控制设计方案的可行性和有效性.
For a class of nonlinear systems, a fuzzy hybrid H 2 / H ∞ sampling control scheme is proposed. The TS fuzzy system is used to characterize the nonlinear system, and the controller is a zero-order-preserving sampled signal. Using the input delay method, the closed-loop system is transformed into a continuous- A new sufficient condition for the existence of fuzzy sampling controllers is given by the Lyapunov - Krasovskii function and the Leibniz Newton formula. The proposed fuzzy sampling control scheme achieves the desired H_2 / H_∞ performance in ensuring system stability The feasibility and effectiveness of the sampling control design are verified by the truck trailer system experiment.
