摘要

摘要

En 中文
本文构建了一种改进的预定义时间方案,用于解决输入量化(IQ)和迟滞非线性切换非线性系统的跟踪控制问题。首先,我们引入量化控制以解决时间采样机制引起的通信资源浪费问题。IQ引入的意外高频分量严重影响系统性能。为克服此问题,提出了一种新的补偿方法,其中通过利用带通滤波器构思了一种新的量化-滤波辅助系统。随后,开发了一种改进的PTL(预定义时间控制),结合滤波参数和量化参数,具有两个主要特点:(1)滤波器与量化器之间存在耦合关系,进一步降低了收敛时间的最小上界和仿真参数整定的复杂性;(2)与传统预定义时间引理相比,具有更快的收敛速率。此外,设计了一种预定义时间滤波器以解决复杂度爆炸问题。最后,通过数值和实际示例验证了所提出控制策略的有效性。
