Abstract

This paper presents a new methodology to design controllers for boost converters operating in a wide range of load variation. The proposed technique uses genetic algorithm to find local LQR controllers providing optimal performance in terms of overshoot and ITSE criteria. Fuzzy logic strategy is then used to combine these local controllers, yielding a strategy that guarantees good performance for a large set of load conditions. The proposed approach is compared with a conventional technique based on a single controller and with a strategy of switching controllers. Simulation results illustrate the superior performance of the converter with the proposed controller.
大负载范围下升压变换器的多控制器:基于遗传算法和模糊逻辑的方法
本文提出了一种新的方法来设计在大范围负载变化下工作的升压变换器的控制器。提出的技术使用遗传算法来寻找在超调和ITSE标准方面提供最佳性能的局部LQR控制器。然后使用模糊逻辑策略将这些本地控制器组合在一起,产生一种策略,保证在大量负载条件下具有良好的性能。将该方法与传统的基于单控制器和切换控制器策略的方法进行了比较。仿真结果表明,采用该控制器的变换器具有良好的性能。
