Abstract
Modern electromagnetic actuators, in particular proportional solenoids, are complex mechatronic systems, including both an actuator and its control system. Electromagnetic actuators are often used in control systems of increased liability and therefore continuously evolving. The development of new types of electromagnetic actuators is based on experimental configuring of parameters of regulators and comprehensive product testing. The complexity and the continuous improvement of the currently used magnetic systems require new approaches to the management of high-precision position of the movable elements. This article discusses an integrated approach to research, monitoring, diagnostics and control of DC proportional solenoids. This approach is based on sensorless measuring of the complex flux-ampere characteristics of the electromagnetic system employed detecting malfunctions, and for determining the position of the movable drive member.
