This paper investigates the problem of bumpless transfer control for switched impulsive positive systems with L-gain performance. For switched impulsive positive systems, the control bump is brought from both switching behavior and impulsive effects. First, the concept of bumpless transfer performance is proposed by imposing magnitude constraints on the control signal to measure the level of bumpless transfer in the switched impulsive positive system. Then, based on a new class of multiple piecewise-continuous copositive Lyapunov function, a tighter mode-dependent average dwell time switching signal bound and bumpless transfer controller are designed to realize positive property, bumpless transfer and L-gain performance of the closed-loop systems. Finally, the feasibility and superiority of the proposed control strategy are illustrated by simulations.
本文研究了具有L增益性能的切换脉冲正系统的无冲击转移控制问题。对于切换脉冲正系统，控制冲击来自切换行为和脉冲效应。首先，通过对控制信号施加幅值约束，提出了无冲击转移性能的概念，以衡量切换脉冲正系统中的无冲击转移水平。然后，基于一类新的多分段连续共正Lyapunov函数，设计了更严格的依赖模式的平均驻留时间切换信号界和无冲击转移控制器，以实现闭环系统的正性、无冲击转移和L增益性能。最后，通过仿真说明了所提控制策略的可行性和优越性。
