摘要为了改善Buck-Boost变换器的动态性能和静态性能,基于无源控制实现变换器电感电流期望值的实时观测,再与协同控制相结合得出控制律,提出了协同无源控制的Buck-Boost变换器实现其高性能控制并使之兼具强鲁棒性。为了简化控制器结构,选取协同控制宏变量时未引入积分环节,易于实时实现。最后,采用基于模型设计的开发流程和自动代码生成技术,开发协同无源控制的Buck-Boost变换器样机,通过系统的仿真研究和样机的实验测试,验证该变换器的动态和静态控制性能。

Abstract：To improve the dynamic and steady performance of Buck-Boost converter, the passivity-based control is introduced to implement the real-time observation of the inductance current. And then, combined with the synergetic control, the control law is obtained, that is, the synergetic and passivity control is suggested to implement the high performance control and strong robustness of Buck-Boost converter. During the process in selecting macro variables of synergetic control, the integral parts are neglected to simplify the controller structure. Furthermore, by adopting the model- based development procedures and the automatic code generation technology, the experimental prototype of synergetic and passive controlled Buck-Boost converter is developed. The simulation and experimental test validate the dynamic state and steady state controlled performance of the proposed converter.

Key words： Buck-Boost converter synergetic and passivity control robustness model-based design automatic code generation
