Anusree Rajan, Pavankumar Tallapragada

AI总结:

本文针对带外部扰动的非线性系统提出事件触发参数化控制方法,设计事件触发规则保证闭环系统全局一致最终有界,并证明事件间隔时间存在一致正下界以排除Zeno行为。

摘要:

本文研究具有外部扰动的非线性系统的事件触发参数化控制(ETPC)。在该控制方法中,在两次连续事件之间,施加到被控对象的每个控制输入是一组线性无关标量函数的线性组合。在每个事件时刻,控制器更新参数化控制输入的系数,以最小化逼近连续时间控制信号的误差,并将更新后的系数传递给执行器。我们设计了一种事件触发规则(ETR),保证闭环系统轨迹的全局一致最终有界性。我们还通过证明事件间隔时间(IETs)存在一致的正下界来确保不存在Zeno行为。我们通过数值算例说明了所得结果。

英文摘要:

This paper deals with event-triggered parameterized control (ETPC) of nonlinear systems with external disturbances. In this control method, between two successive events, each control input to the plant is a linear combination of a set of linearly independent scalar functions. At each event, the controller updates the coefficients of the parameterized control input so as to minimize the error in approximating a continuous time control signal and communicates the same to the actuator. We design an event-triggering rule (ETR) that guarantees global uniform ultimate boundedness of trajectories of the closed loop system. We also ensure the absence of Zeno behavior by showing the existence of a uniform positive lower bound on the inter-event times (IETs). We illustrate our results through numerical examples.
