【摘要】 Buck变换器具有器件少、控制简单等优点,已被广泛应用于微处理器供电的电压模块构架中,但目前工程上的Buck电路大多采用常规PID控制器,存在着参数整定复杂,调试时间长等缺点。通过把模糊控制器与PID控制器相结合,利用模糊逻辑控制实现了PID控制器参数在线自调整。理论分析和仿真结果表明,采用自适应PID控制具有更多的优点。更多还原

【Abstract】 Buck converter with smaller part and simple control,etc.,is widely used in microprocessor power supply voltage of the module architecture.Most of the current engineering buck circuit uses conventional PID controller.But there are some problems,such as parameters tuning complexity,debugging with longer time,and other shortcomings.Combined with the fuzzy controller and PID controller,the PID controller parameters is realized on-line self-tuning by using fuzzy logic control.Theoretical analysis and simulation result show that the adaptive PID control has more advantages.更多还原
