摘要
针对开关电源Buck变换器在非线性控制传统的PID调节控制的不足,提出了一种新的模糊控制和PID控制相结合的方法。以Buck电路为例并通过Matlab中的Simulink进行了仿真实验。实验结果证明,模糊PID控制有超调小、响应快、抵御外界扰动能力强的优点。
In response to deal with the weakness of the PID control in the switching mode power supply,a new intelligent control method based on the fuzzy control and PID control was presented.The buck circuit was taken as an example,and simulation experiment was carried out under the Matlab/Simulink.The experiment results indicate that by comparison with the PID control,the fuzzy control has a lot of merits,such as small turn-on overshoot,fast transient response and small voltage fluctuations with output current changes.
