Hybrid and cyber-physical systems pose new challenges for formal construction of systems. In hybrid systems, the states evolve over continuous time according to related laws of continuous and discrete dynamics. Thus, timing constraints and synchronous signals play important roles. Moreover, in the development of complex hybrid systems, refinement, and composition of timing constraints are in need. However, the existing formal approaches of Event-B have difficulties in refinement and composition of hybrid systems. Therefore, in this article, we propose a formal hybrid approach to solve this problem. Our approach of modeling is based on the Event-B method, and uses the Rodin platform and its plugin Theory.

使用 Event-B 对混合系统中的时序约束进行建模

混合和网络物理系统对系统的正式构建提出了新的挑战。在混合系统中，状态根据连续和离散动力学的相关定律在连续时间内演化。因此，时序约束和同步信号起着重要作用。此外，在复杂混合系统的开发中，需要改进和组合时序约束。然而，现有的 Event-B 形式化方法在混合系统的细化和组合方面存在困难。因此，在本文中，我们提出了一种形式化的混合方法来解决这个问题。我们的建模方法基于 Event-B 方法，并使用 Rodin 平台及其插件 Theory。
