摘要

摘要: 针对非线性多智能体系统, 提出基于混合双端事件触发机制的模糊跟踪控制策略. 首先, 相比于现存状态事件触发机制, 构建了一种灵活可调的阈值设计方法以满足系统实时性需求; 其次, 改进的状态触发机制将状态估计值作为触发信号, 可有效降低现存机制的保守性并提高阈值设计的灵活性; 随后, 针对控制器-执行器环节和传感器-控制器环节, 设计了混合双端事件触发机制来同时缓解双信道的通讯负担. 此外, 为了解决未知不可测状态的问题, 构造了一种仅基于相对输出信息的状态观测器. 最后, 在闭环系统内, 所有信号都是半全局一致最终稳定的, 并用一个实际的仿真例子证明了提出控制策略的有效性.

Abstract: For nonlinear multiagent systems, this paper proposes the fuzzy tracking control strategy based on hybrid dual-terminal event-triggered mechanism. First of all, compared with existing state triggering mechanisms, an adjustable threshold designing method is constructed, which meets the real-time performance requirements of the system. Moreover, the improved state triggering mechanism considers the estimated state signal as the trigger signal, which effectively reduces the conservatism of existing mechanisms and enhances the flexibility of threshold design. Subsequently, the hybrid dual-terminal event-triggered mechanism is designed for controller to actuator link and sensor to controller link, which releases dual channel communication pressure, simultaneously. Besides, to solve the problem of unknown unmeasurable state, the state observer is constructed, which bases solely on relative output information. Finally, all the signals are semiglobally uniformly ultimately bounded in the closed-loop system, and a practical simulation example demonstrates the feasibility of the proposed control strategy.
