摘要
在本文中,我们考虑了开关非线性多输入多输出(MIMO)延迟系统的基于开关指令过滤的自适应模糊输出反馈漏斗控制问题。为每个子系统构建了一个开关式 MIMO 高增益状态观测器,以估计不可用的系统状态。与传统的指令滤波技术相比,其主要优势在于为每个切换子系统设计了改进的误差补偿信号,以消除滤波误差,避免复杂性爆炸和奇异性问题。与传统的 Lyapunov-Krasovskii 函数方法不同的是,通过使用适当的多重 Lyapunov-Krasovskii 函数并结合模糊逻辑系统的近似能力,可以克服开关延迟系统因未知时间延迟而产生的设计障碍。在一类平均停留时间取决于模式的开关信号下,闭环开关系统中的所有信号在输出反馈控制下都是半全局均匀终极约束的;同时,跟踪误差可以保持在预先指定的性能漏斗内。案例研究说明了拟议控制方法的灵活性和有效性。
Switched Command-Filtered-Based Adaptive Fuzzy Output-Feedback Funnel Control for Switched Nonlinear MIMO-Delayed Systems
In this article, we consider the problem of switched-command-filtered-based adaptive fuzzy output-feedback funnel control for switched nonlinear multi-input multi-output (MIMO) delayed systems. A switched MIMO high-gain state observer is constructed for each subsystem to estimate unavailable system states. Compared with the conventional command filter technique, the main advantage is that the improved error-compensating signals are designed for each switched subsystem to remove the filtered errors and avoid an explosion of complexity and the singularity problem. Different from the traditional Lyapunov--Krasovskii functional method, design obstacles stemming from unknown time delays are overcome for the switched delayed systems by using appropriate multiple Lyapunov--Krasovskii functions and combining with the approximation capability of the fuzzy logic systems. Under a category of switching signals with mode-dependent average dwell time, all signals in the closed-loop switched system are semiglobally uniformly ultimate bounded under the output-feedback control; meanwhile, the tracking errors can remain in prespecified performance funnels. Case studies illustrate the flexibility and effectiveness of the proposed control approach.
