Adaptive Control of DC-DC Converter Using Simulated Annealing Optimization Method

Abstract

The purpose of this paper is to present a new adaptive control method used to adjust the output voltage and current of DC-DC (DC: Direct Current) power converter under different sudden changes in load. The controller is a PID controller (Proportional, Integrator, and Differentiator). The gains of the PID controller (KP, KI and KD) tuned using Simulated Annealing (SA) algorithm which is part of Generic Probabilistic Metaheuristic family. The new control system is expected to have a fast transient response feature, with less undershoot of the output voltage and less overshoot of the reactor current. Pulse Width Modulation (PWM) will be utilized to switch the power electronic devices.

Metaheuristic algorithms for PID controller parameters tuning: review, approaches and open problems

“…SA has been applied for tuning PID parameters of different processes like AVR system (Lahcene et al, 2017), attitude control system for a re-entry capsule (Vijay and Banu, 2016) and DC-DC power converters (Alqudah et al, 2014). Further readings on application of SA can be seen in Siddique and Adeli (2016); Suman and Kumar (2006); Sibalija (2018); Varty (2017).…”

Load balancing of heterogeneous parallel DC-DC converter

“…In contrast, metaheuristic methods are considered to be generally applicable methods of solution. It is recommended to use metaheuristic methods to solve problems where there is a risk of being deadlocked in local maximum or minimum [11]. …”
