Messages & Events
R2026b使用 Messages & Events 库中的模块对组件之间基于消息的通信进行建模。在分布式控制系统架构中，当由于系统复杂性而难以实现集中式方法时，基于消息的通信是必要的。消息将事件和相关数据结合在一起，允许组件通信而不要求同时执行。

精选示例
Establish Message Send and Receive Interfaces Between Software Components
Create message send and receive interfaces, and prepare components for C++ code generation.
Schedule Time Hits and Function-Call Events During Simulation
Use the Hit Scheduler block to schedule time hits and function-call events based on the runtime behavior of a system. The model in this example represents a traffic camera system that captures images of speeding vehicles. The Hit Scheduler block schedules time hits for the simulation based on runtime computations that determine when the camera should capture an image.
Model Effect of Temperature and Jitter on Crystal Oscillation Frequency
Use the Hit Scheduler block to model temperature drift and jitter in crystal oscillator frequency.
信息物理系统建模
