Special Issue Information

Dear Colleagues,

Electromagnetic actuators have been mostly used in mechatronics applications when high-speed, high-precision, and contactless effects have been required. Their mechanical design needs to be optimal to mitigate the energy demand. Modeling of these actuators is challenging, and their behaviors exhibit nonlinear dynamics. As high performance is required, these actuators must interact digitally with innovative control systems. Cooperative actuators are an interesting class of this new actuator and require very special control systems. These actuators are suitable for all application fields, from micro systems to large mechanical systems.

Contributions from all fields related to innovative electromagnetic actuators are welcome to this Special Issue, particularly the following:

  • Electromagnetic actuators: state-of-the-art, digitalization, applications, case studies, project reports;
  • Design of innovative electromagnetic actuators: optimal design, fabrication, EMC, modeling and simulation, system-identification of dynamics;
  • High-speed and/or high-accurate and cooperative actuators;
  • Digital control of electromagnetic actuator: robust, nonlinear, MPC, data-based control-systems;
  • Design of electromagnetic actuator testbeds for education purpose.

As the rotational speed of conventional rotor systems supported by oil-film bearings has increased, vibration problems such as oil whip and oil whirl have become apparent. Our group proposed the use of active magnetic bearings (AMBs)/bearingless motors (BELMs) to stabilize these systems. In such a system, measuring the variable stiffness and damping of the oil-film bearings, the current-force and displacement-force parameters of the AMBs/BELMs, and the residual unbalanced force is necessary to satisfy the stability of the rotor system. These parameters are the foundation for the rotor dynamics analysis and optimization of the control strategy. In this paper, we propose a method to simultaneously identify the parameters of the oil-film bearings and AMBs/BELMs along with the residual unbalanced forces during the unbalanced vibration of the rotor. The proposed method requires independent rotor responses and control currents to form a regression equation to estimate all the unknown parameters. Independent rotor responses are realized by changing the PID control parameters of the AMBs/BELMs. Numerical simulation results show that the proposed method is highly accurate and has good robustness to measurement noise. The experimental results show that the unknown parameters identified by the responses generated by different controller parameters are similar. To confirm that the identification results are correct, verification experiments were carried out. The vibration amplitude of the rotor was successfully suppressed by applying a force to the rotor in the opposite direction to the residual unbalanced force. The frequency response characteristics and unbalanced responses of the rotor estimated by the values of the parameters identified show good consistency with the measured results. Full article
