摘要

对于开关时延系统,利用多片式 Lyapunov-Krasovskii 函数方法研究了无缓冲转移控制问题。首先,提出了依赖时延的无缓冲传输概念,以描述切换时延系统的瞬态性能,该概念同时限制了当前状态和时延状态的振幅颠簸。其次,设计了具有规定时间的状态相关切换信号,以避免频繁切换。开发了时变开关控制器,以减少控制颠簸。第三,在实现渐近稳定性的前提下,通过放宽传统的无缓冲转移条件,推导出确保无缓冲转移性能令人满意的可解性条件。最后,以航空发动机控制系统为例,展示了所提方法的有效性。

Bumpless transfer control for switched time-delay systems with application to aero-engine control
For switched time-delay systems, the bumpless transfer control issue is investigated by utilizing the multiple piecewise Lyapunov–Krasovskii function approach. First, a time-delay-dependent bumpless transfer concept is put forward to depict the transient performance of switched time-delay systems, which restricts the bumps in the amplitude of the present state and the time-delay state, simultaneously. Second, a state-dependent switching signal with a prescribed time is designed to avoid switching frequently. A time-varying switching controller is developed to decrease control bumps. Third, under the premise of achieving asymptotic stability, a solvability condition ensuring a satisfactory bumpless transfer performance is derived through relaxing the traditional bumpless transfer condition. Finally, an instance of the aero-engine control system is used for exhibiting the validity of the presented method.
