基于模型的多任务数字电源控制系统设计

首先分析了多任务电源控制系统的工作机制，在此基础上对电源控制系统的任务进行了合理规划和优先级别划分，并建立了控制系统的仿真模型，进一步结合Matlab／EmbeddedCoder集成外设驱动并生成了控制系统的工程代码，并基于SimPowersystem建立了半桥DC／DC的平均电路模型，并通过处理器在环测试（PIL）对控制算法进行了验证，最后通过了样机测试。

Model-based Design and Verification of a Multi-tasking Digital Power Control System

First, the working mechanism of the multi-tasking power control system are analyzed. Then, rational planning and prioritization is made for different control tasks according to the task features and a control system model are established. Combined with Matlab/Embedded Coder, peripheral drivers are integrated and the production-quality C source code of the controller is also generated and a half-bridge DC/DC simulation model based on Sim Power system is constructed and the core control algorithm is verified through processor-in-the-loop （PIL） testing. Finally, a prototype is built to verify the proposed control system.
