基于DSP芯片的开关电源的改进PID设计

Improved Design of Switching Power Supply PID Based on DSP Chip1

本文提出了一种开关电源改进型PID设计和MATLAB仿真方法。仿真结果表明:改进的PID动态响应快、超调量小,控制简单、易于实现。

This paper presents a method of improved design and MATLAB simulation of switching power supply PID. The experiment results indicate that the improved PID control, compared to the traditional PID control and the integral-detached PID control, has a lot of merits, such as fast transient response, small turn-on overshoot and simple control processing.
