This paper presents an efficient and accurate dynamical model of reluctance actuators, suitable for prediction and control applications. It is a hybrid lumped-parameter state-space model that takes into account the mechanical and electromagnetic dynamics, including eddy currents, flux fringing, magnetic hysteresis and saturation. Special emphasis is placed on the hysteresis model, which is based on the Jiles–Atherton theory. The novel parts of the model – the gap reluctance expression and the modified Jiles–Atherton hysteresis model – are identified, showing that the simulated results fit very well the experimental data. Furthermore, its potential application for control is exemplified with a feedback strategy, in which the design of the controller and observer are based on the proposed dynamical model.

本文提出了一种适用于预测和控制应用的磁阻执行器的高效，准确的动力学模型。它是一个混合的集总参数状态空间模型，考虑了机械和电磁动力学，包括涡流，磁通流化，磁滞和饱和。磁滞模型特别受重视，该模型基于吉尔斯-阿瑟顿理论。确定了模型的新颖部分-间隙磁阻表达式和改进的Jiles-Atherton磁滞模型-表明模拟结果与实验数据非常吻合。此外，其在控制方面的潜在应用以反馈策略为例，其中控制器和观测器的设计均基于所提出的动力学模型。
