Buck型DC-DC变换器中单输入模糊控制器的设计与实现
Design and implementation of single input fuzzy controller for Buck DC-DC converter
摘要
Abstract
A simplified fuzzy control algorithm used for digitally controlled DC-DC converters, the single input fuzzy control algorithm, is proposed. In this algorithm, the signed distance method is introduced to simplify the two inputs in the conventional fuzzy control algorithm to a single input, making the number of the corresponding fuzzy rules significantly reduced. On this basis, the single input fuzzy controller is designed by the field-programmable gate array (FPGA), and the final verification is performed. The experimental results show that for the Buck DC-DC switching converter, when the input voltage is 2.7 to 3.5 V and the output voltage is 0. 8 to 1.5 V, the set-up time is less than 150 ms and the steady-state error is less than 10 mV. Compared with the conventional fuzzy controller, the single input fuzzy controller has simpler hardware implementation in design, regulation and implementation. Therefore, it may be widely used in digitally controlled DC-DC converters.关键词
