Controlling Switched Dc-Dc Converter Using ANFIS in Comparison with PID Controller

Abstract

The non-linear behaviour of the Dc-Dc converters which appears mainly because of different causes such as disturbances, aging of materials, source instability which makes control process as a difficult task to overcome, many control techniques are employed such as PID controllers which works under linear operating conditions and fails with non-linear systems, so in order to reach a good dynamics, good performance and a good insensitivity to perturbations and parameter uncertainties, an artificial intelligence control strategy namely ANFIS has been used which does not need the mathematical model of the plant and automatically overcome the changing conditions as well. In this paper, a MATLAB/Simulink inspection is established to design a prototype model for such a converter with two different control principles (PID, and ANFIS) for Comparative purposes. In ANFIS controller two input parameters and one output (error signal, and rate of change in error) are considered, this voltage controller ensures better dynamic behaviour and superior performance compared to PID controller in regulating the output voltage.

Hybrid Controlled Multi-Input DC/DC Converter for Electric Vehicle Application

“…Te authors of [30] propose a multi-input nonisolated interleaved DC-DC converter using coupled-inductor techniques. ANFIS was used to manage the voltage of a DC-DC converter [31] and to reduce error values [32]. Furthermore, a traditional controller did not enable reliable speed tracking of a predetermined speed profle when the converter is utilized for an EV application.…”
