Abstract

The DC-DC converters are extensively used in modern telecommunication and consumer electronics. Stability is one of the most aspect in designing of automatic control of DC-DC buck converter. In this paper a discrete auto-tuning PID scheme is developed for DC-DC converters for fast response time. When the required output does not follow the set point, a controller for synchronous buck converter is to be used with objective of keeping the error as minimum. The algorithm is used for the tuning discrete PID controller to obtain its parameters with a minimum error and is applied to Synchronous buck converter to improve its performance. For fast transient response, settling time and rise time of the Converter, the controller gains are continuously modified. For its implementation a buck converter is designed and its MATLAB/Simulink model is developed. The simulation results describes the effectiveness of the developed algorithms.

用自整定PID控制器改善DC - DC变换器的瞬态响应

DC-DC变换器广泛应用于现代通信和消费电子产品中。稳定性是DC-DC降压变换器自动控制设计中最重要的考虑因素之一。为了提高直流-直流变换器的响应速度，本文提出了一种离散自整定PID方案。当所需输出不符合设定值时，采用同步降压变换器控制器，目的是使误差最小。将该算法用于离散PID控制器的整定，使其参数误差最小，并应用于同步降压变换器中，以提高其性能。为了快速的瞬态响应、稳定时间和上升时间，控制器的增益被连续修改。为此，设计了一种降压变换器，并建立了其MATLAB/Simulink模型。仿真结果表明了所提出算法的有效性。
