The parallel part control consists of a Proportion-Integral (PI) control and a regular time hysteresis PWM control. The Series part control adopts a triangle wine-linear PWM control.
A distributed control structure is proposed. The basic structure, series extended structure and parallel extended structure are defined.
提出一种分布式控制结构，定义了基本运行结构、串行扩展结构和并行扩展结构。
