摘　　要：为了进一步提高BUCK变换器的控制性能,提出了一种基于互补滑模观测器的BUCK变换器互补滑模控制方法。首先,建立了含有参数摄动和未建模动态的BUCK变换器模型,得到了BUCK变换器非线性模型;其次,结合互补滑模控制理论提出了一种互补滑模观测器,有效提高了对集总扰动的观测精度,并结合互补滑模控制设计控制器;最后,使用处理器在环测试平台与基于传统滑模观测器的滑模控制方法进行对比,结果验证了所提控制方法的优越性和有效性。In order to further improve the disturbance resistance of the BUCK converter,this paper proposes a complementary sliding mode control method for the BUCK converter based on a complementary sliding mode observer.Firstly,a BUCK converter model with parameter perturbations and unmodeled dynamics was established,and a nonlinear model of the BUCK converter was obtained.Secondly,a complementary sliding mode observer is proposed based on the theory of complementary sliding mode control,which effectively improves the observation accuracy of lumped disturbances.Design a controller using complementary sliding mode control.Finally,the superiority and effectiveness of the proposed control method were verified by comparing it with the sliding mode control method based on traditional sliding mode observer using a processor on the loop testing platform.
