Abstract

Currently, real-time force control of actuators is one of the most important issues found in different branches of industry. In order to achieve the best performance of a given electromagnetic actuator, first of all, the parameters of the dynamic model of the actuator should be identified. In this research, an experimental platform is designed and manufactured to conduct experiments and identify the parameters of the electromagnetic actuator. The process of generating a reference signal for identification is performed in a real-time manner by the STM32F746ZG board. The ARM-Cortex M7 microcontroller on the board has provided us with the ability to produce any type of signal with the desired frequency, amplitude and bias. In this research, a harmonic chirp signal is generated to study the behavior of the actuator at different frequency intervals. The amplitude of inertial force generated by the actuator is measured by a Kistler Type 9255B dynamometer. Finally, by analyzing the system response, the accurate dynamic model for the system is successfully estimated.
