“…In the PID control, K p effects the rise time, K i reduce the steady state error and K d is used to reduce the overshoot and improve the stability. [14,15].These controller parameters are defined optimally in the control system to make the system stability and obtain an effective or robust transient response. As can be seen from Fig.…”

“…In recent years, artificial intelligence and optimization techniques have been used frequently in designing of PID depending on development of these methods. Algorithms like Fuzzy Logic (FL) [11], [12], Particle Swarm Optimization (PSO) [13], [14], Bacterial Foraging Optimization (BFO) [15], [16] or Genetic Algorithm (GA) [17], [18] have been implemented to determining the PID gain parameters successfully. However, they have had inadequate in some solution process due to reasons like difficulty of creating fuzzy rules in fuzzy logic, premature convergence or long computing time.…”

In this study, Artificial Bee Colony (ABC) algorithm is proposed to determine gain parameters of the PID algorithm for controlling a designed buck converter. Study aims to improve the performance of buck converter via ABC-PID. Genetic Algorithm (GA) based PID is used also to control the converter in order to investigate the performance of the proposed algorithm on the system. Experiments with different cases are done via simulations. In the simulations, settling time, steady-state error and readjustment time of output voltage in cases of load variation are analyzed in order to determine the performance of the proposed algorithm. Results obtained from simulations are shows that ABC-PID controlled converter has superior performance than GA-PID controlled buck converter. 

In this paper, author proposes study of two-loop voltage mode controlled (TVMC) buck converter for improved transient and dynamic performance under line and load disturbances. Buck converter with voltage mode control will improve efficiency, but transient response is sluggish. It requires large filter capacitor. Two-loop voltage control technique is proposed to improve output voltage regulation irrespective of line and load disturbances, and to achieve fast transient response. The two-loop voltage control technique has many advantages over conventional voltage mode control technique, such as fast transient response and reduced peak overshoot etc. Simulation model of TVMC buck converter is developed in MATLAB/Simulink and extensive result analysis has been made. The result analysis shows the effectiveness and significant improvement of the proposed control technique.

“…Instead of feeding the buck converter by an ideal constant DC voltage source, a three phase full bridge rectifier has been used to feed the buck converter to check the effect of input voltage fluctuations or changes more realistically because the input of buck converter is usually obtained by rectifying the line voltage. Therefore, the input voltage of buck converter changes due to the fluctuations in line voltage magnitudes [4], [5]. Moreover, in order to check the response of a motor, the output of the buck converter is then fed to a three-leveldiode clamped inverter as shown in Fig.…”

Power electronic converters play a vital role in a power system and the most commonly used type of DC/DC converters is buck converter. This is due to the fact that buck converters are widely used to step down the voltage as well as they provide good voltage regulation in critical applications including power supplies for data centers. Therefore, designing a buck converter that gives a regulated output, acceptable for switch mode power supplies is still challenging task. A closed loop buck converter mitigates the problems such as input voltage unstability or variation. This paper discusses the effects of input voltage variations on the open loop and closed loop models of buck converter. VoltageMode Control (VMC) has been proposed to develop an efficient closed loop system in order to avoid voltage fluctuations at the output of the buck converter.
