“…In the past, they have been controlled predominately by analogue integrated circuit technology with linear system design techniques [1][2][3]. Digital controller applications and their ability to incorporate advanced control schemes [4][5][6][7][8] have become very popular for controlling DC-DC converters. Fuzzy-logic control (FLC) is one of the more attractive and promising control methods from amongst many digital control approaches.…”

Adaptive fuzzy-logic state controller for DC–DC step-down converter

et al. 2017

This paper deals with the implementation of a control algorithm based on a state controller with an adaptation of the state controller gains by using the fuzzy-logic approach. Adjustable state controller gains cause that the static error can be reduced arbitrarily for a system with variable parameters as is the DC-DC step-down converter for power supply systems. Fuzzy sets are tuned offline by a genetic algorithm using fuzzy-logic and a genetic toolbox in MATLAB. Fuzzification and defuzzification algorithms are implemented in real time within a Field Programmable Gate Array circuit. The whole control algorithm is performed within a sampling time of 5.33 µs. Operation of the controller is verified experimentally.

“…With the rapid development of digital circuits, the digital control systems will gradually replace the currently used analogue controllers in high frequency switching converters. Among many digital control methods, the classic current mode control and its digital implementation is the matter of many research interests [4][5][6][7][8][9][10][11]. Microprocessors were unable to compute the necessary calculations for the control algorithm fast enough within the switching period.…”

“…Microprocessors were unable to compute the necessary calculations for the control algorithm fast enough within the switching period. Later, advances in digital technology prompted some research groups to use FieldProgrammable Gate Arrays (FPGA's) [4], programmable IC's [5] and Digital Signal Processors (DSP's), [6][7][8][9][10][11]. In the current mode, the switch or the inductor current is sensed within an inner loop and replaces the conventional current controller and saw-tooth waveform for the Pulse Width Modulator (PWM) generating function (Figs.…”

This paper introduces a digitally performed voltage and current control mode for dc-dc step up converter based on FPGA technology. The voltage and current measurement was realized by using A/D converters as peripheral units of the FPGA system. Special attention was performed with current measurement and its A/D conversion due to the used predictive current mode algorithm which enables the fully digitalization of the whole control processes.
