分布式控制系统中IEC功能块的并行化策略

Paralleling IEC function blocks in distributed control systems

针对IEC61499标准下分布式控制系统的特点,引入流水线并行思想,在单回路和复杂控制系统中分别实现了IEC功能块的并行化处理,并对其优越性进行了分析。应用实例仿真结果表明,相对于常规集中式控制器,采用功能块并行化策略后系统采样周期大大降低,从而提高了控制品质。

The pipeline parallelism was employed for IEC61499 compliant distributed control systems. Paralleling strategies for IEC function blocks in single-loop and complex control systems were proposed respectively. An illustrative example was presented, highlighting the advantages of the proposed strategies. Compared with conventional control systems with centralized controllers, IEC function block based on distributed control systems with pipeline parallelism provides shortened sampling period, which results in better control performance.
