摘要

本文介绍了一种五自由度飞轮储能系统的结构。利用拉格朗日方程建立了FESS中主动磁轴承系统的非线性模型。在该模型中，每个线圈中的电流被视为状态变量，控制输入是施加到每个线圈上的电压，这种方法比电流控制输入方法更具优势。针对非线性多输入多输出(MIMO)系统，提出了分散结构的PID控制器。在仿真结果中讨论了磁悬浮轴承飞轮的动态特性和控制器的性能。

Nonlinear Modeling and Control of Active Magnetic Bearings for a Flywheel Energy Storage System

In this study, a structure of a five degree of freedom flywheel energy storage system (FESS) is introduced. A nonlinear model of active magnetic bearing (AMB) system in the FESS is obtained by Lagrange's equation. In this model, the current in each coil is treated as a state variable and the control input is the voltage applied to each coil, this approach offers more advantages than current control input approach. PID controllers with decentralized structure are proposed to control the nonlinear multiple-input multiple-output (MIMO) system. Dynamic behavior of the flywheel in magnetic bearings and performance of the controller is discussed in simulation results.
