摘要

本文提出了一种新的多单元变换器(三个单元)控制策略，以驱动直流电机，主要有两个目标:1)确保飞行电容器电压的适当分布，这意味着电容器之间的电压调节;2)将直流电机的速度调节到所需的水平。该系统采用四阶非线性数学模型进行描述。为了稳定全局系统并实现上述目标，综合了一种基于微分平面度方法的控制器来控制该系统。在Matlab/SimPowerSystems环境下进行了仿真，结果表明所设计的控制器达到了预期目标。

Flatness based control of multicellular power converter feeding DC motor

In this paper, a new control strategy of a multicellular converter (three cells) is proposed in order to drive a DC machine, there were two main goals to achieve: i) ensure a suitable distribution of flying capacitors voltage which implying the regulation of voltages across capacitors, ii) regulating DC motor velocity to a desired level. The proposed system is described by 4th order nonlinear mathematical model. To stabilize the global system and realize the above objectives, a controller based on differential flatness approach is synthesized in order to control this system. The simulation results have been performed through Matlab/SimPowerSystems environment and show that the designed controller meets its objective.
