本文针对基于DC/DC变换器模型的控制方法在模型失配方面的局限性，提出了一种基于无模型自适应控制的方法。建立了紧格式MFAC动态线性化泛模型，设计了DC-DC变换器的无模型自适应控制器。控制器不需要受控系统的数学模型及相关先验知识，仅利用系统I/O数据进行控制器设计，解决了变换器模型失配的问题。进行了Simulink仿真，仿真结果表明，相比于传统的基于模型的控制方法，本文所用方法能克服模型失配，具有更好的适应性和鲁棒性。

In this paper, based on the DC-DC converter control method of the model mismatch in the model's limitations, A method of MFAC is proposed. Model-free adaptive control (MFAC) is a kind of control er design methods which needs less knowledge of mathematical models and relevant prior knowledge, and only needs the I/O data to design the control er. A compact format MFAC linear dynamic universal model, design a model free adaptive control er for DC-DC converter. It can be used to solve the problems of model mismatch. The simulation model of DC-DC converter is established by analyzing the character of model, The MFAC can overcome the model mismatch, has bet er adaptability and robustness.
