A major challenge in networked control systems is to reduce the use of shared communication and control resources without compromising the performance of the closed-loop system. Motivated by this challenge, this paper presents an observer-based controller with irregular sampling that reduces the control attention and guarantees closed-loop stability and global ultimate boundedness of the plant's state vector regardless of bounded input and output disturbances. The feedback control design is based on self-triggered control, whereas the observer is based on the block-form state-space representation of the plant. It is shown via analysis and simulation that the overall control law decreases the number of samples without loosing observability and closed-loop stability, reducing the utilization of communication resources.

线性网络控制系统的自触发减少注意力输出反馈控制


网络控制系统的一个主要挑战是在不影响闭环系统性能的情况下减少共享通信和控制资源的使用。受这一挑战的启发，本文提出了一种基于观测器的控制器，具有不规则采样，可以减少控制注意力，并保证闭环稳定性和对象状态向量的全局最终有界性，无论有界输入和输出扰动如何。反馈控制设计基于自触发控制，而观测器基于对象的块状状态空间表示。分析和仿真表明，总体控制律在不损失可观测性和闭环稳定性的情况下减少了样本数量，降低了通信资源的利用率。
