Several modeling, estimation, and control strategies have been recently presented for simple reluctance devices like solenoid valves and electromagnetic switches. In this paper, we present a new algorithm to online estimate the flux linkage and the electrical time-variant parameters of these devices, namely the resistance and the inductance, only by making use of discrete-time measurements of voltage and current. The algorithm, which is robust against measurement noise, is able to deal with temperature variations of the device and provides accurate estimations during the motion of the armature. Additionally, an integral estimator that uses the start of each operation of the actuator as reset condition has been also implemented for comparative purposes. The performances of both estimation methods are studied and compared by means of simulations and experimental tests, and the benefits of our proposal are emphasized. Possible uses of the estimates and further modeling developments are also described and discussed.

磁阻执行器的实时电磁估计


最近针对电磁阀和电磁开关等简单磁阻装置提出了几种建模、估计和控制策略。在本文中，我们提出了一种新算法，仅通过使用电压和电流的离散时间测量来在线估计这些设备的磁链和电气时变参数，即电阻和电感。该算法对测量噪声具有鲁棒性，能够处理设备的温度变化，并在电枢运动期间提供准确的估计。此外，出于比较目的，还实现了使用执行器每次操作的开始作为重置条件的积分估计器。通过模拟和实验测试对两种估计方法的性能进行了研究和比较，并强调了我们建议的优点。还描述和讨论了估计的可能用途和进一步的建模开发。
