Design of Adaptive Fuzzy Logic Controller for Auto-adjustable DC-DC Converters

摘要：

This paper introduces an approach for the design of an adaptive non-linear digital Fuzzy logic controller for a digital controlled auto-adjustable Buck DC-DC converter, which is validated by Simulink tools of Matlab. The setup time of the output voltage was about 10μ.s and the steady state error was less than 2mV with the proposed controller. When the supply voltage or load current was disturbed, the output reached stability again after 15μs. And the output voltage tracked the change of the reference voltage in 15μs. The results show that its dynamic response was quick and its sensitivity was very interesting for various supply voltages and load resistance variations.
