摘要
为提高Cuk变换器的性能,提出了一种基于Cuk变换器EL模型的无源控制方法。首先建立Cuk变换器的EL(Euler-Lagrange)模型,根据控制目标,确定Cuk变换器的期望平衡点,基于无源控制理论,采用阻尼注入方法设计Cuk变换器的无源控制器。仿真结果表明,Cuk变换器无源控制器可使Cuk变换器具有良好的动、静性能和对负载变化的鲁棒性。
To improve the performance of Cuk converter, a passivity based control method based on the EL model of the Cuk converter is proposed. The EL model of Cuk converter is set up in this paper. The desired equilibrium point of Cuk converter is determined according to control goal. Based on passivity based control theory, a passivity based controller of Cuk converter is designed by damping injection method. Simulation results show the controller can give Cuk converter good dynamic and static performance and robustness to load.
