Abstract
The system performance of rail vehicles NCS mainly depends on communication performance and control performance. Because of considerably limited availability of computing resources, real-time scheduling of shared resources is among the factors that greatly impact system performance. From a real-time control perspective, the problem of real-time scheduling in NCS is illustrated based on timing analysis of a typical NCS. Take the MVB of rail vehicle NCS for example, The theory and practice of synchronously static Rate Monotonic(RM)are introduced into rail vehicle NCS, with special focus on open-up scheduling and adaptive scheduling, which made communication simplified and reliable. At the same time, build objective function of system performance based on state space equation, wholly benefits optimized design of rail vehicle NCS, considering both communication performance and control performance.
