摘要

比例-谐振(PR)控制器由于具有正、负序“双向谐振”的特性

且无需复杂的旋转坐标变换

在脉宽调制(PWM)变换器控制中具有广泛应用。从工程应用角度出发

系统讨论了PR控制器应用中需注意的3个关键问题:控制器的参数设计与稳定性分析

数字控制实现中的延时影响和相位补偿

以及频率自适应PR控制器的结构与离散化实现。仿真和实验结果验证了所述参数设计方法的合理性、数字延时补偿的有效性以及频率自适应比例-谐振控制器对频率变化的适应能力。

Abstract

Owing to the positive and negative sequence “bi-resonance” feature and no need for complex rotating coordinate transformation

the proportional-resonant (PR) controller is widely used in the control system of the pulse width modulation (PWM) converter. From the engineering point of view

this paper summarizes three key points of the application of the PR controller

i.e.

parameter design method

the impact of the digital control delay and its phase compensation strategy

as well as a frequency adaptive PR controller and its discrete method. Simulation and experimental results have verified the rationality and effectiveness of the parameter design consideration

the effectiveness of digital delay compensation and the frequency adaptive nature of the frequency adaptive PR controller.
