摘要

本文将规定的性能控制方法推广到具有时变传输间隔的离散时间控制。从连续时间PPC方案开始，该方案强制执行预先指定的、用户自定义的输出跟踪误差性能界限，我们开发了一个动态控制协议，实时确定采样时刻。这种方法保留了闭环稳定性和输出跟踪性能，同时允许传输间隔根据当前与性能界限的误差距离变化。通过对采样时间的调整，降低了采样频率，提高了系统的效率和可靠性。此外，我们表明严格的性能要求导致更小的传输间隔，而宽松的要求允许更大的传输间隔。理论分析和仿真结果验证了该方法的有效性。

Discrete-time prescribed performance control with time-varying transmission intervals

This paper extends the prescribed performance control (PPC) methodology to discrete-time control with time-varying transmission intervals. Starting from a continuous-time PPC scheme that enforces pre-specified, user-defined performance bounds on output tracking errors, we develop a dynamic control protocol that determines sampling instants in real-time. This approach preserves closed-loop stability and output tracking performance while allowing transmission intervals to vary according to the current error distance from the performance bounds. By adapting the sampling times accordingly, our method reduces sampling frequency and improves system efficiency and reliability. Furthermore, we show that stricter performance requirements result in smaller transmission intervals, whereas relaxed requirements permit larger ones. Theoretical analysis and simulation results verify the effectiveness of the proposed approach.

期刊介绍： The European Control Association (EUCA) has among its objectives to promote the development of the discipline. Apart from the European Control Conferences, the European Journal of Control is the Association''s main channel for the dissemination of important contributions in the field. The aim of the Journal is to publish high quality papers on the theory and practice of control and systems engineering. The scope of the Journal will be wide and cover all aspects of the discipline including methodologies, techniques and applications. Research in control and systems engineering is necessary to develop new concepts and tools which enhance our understanding and improve our ability to design and implement high performance control systems. Submitted papers should stress the practical motivations and relevance of their results. The design and implementation of a successful control system requires the use of a range of techniques: Modelling Robustness Analysis Identification Optimization Control Law Design Numerical analysis Fault Detection, and so on.
