“…A potential disadvantage of this type of actuator lies in its stable load transport range, which accounts for less than a third of the full range [16]. Numerous techniques have been studied to extend the stable range of motion of these types of actuators, including nonlinear magnetic field mapping [23], double solenoid configuration [24], pulse width modulation control [25], sliding mode control [26], adaptive control [27], and the PID Control that are easy to design and implement [14]. However, the difficult task is to automatically and accurately adjust PID gains in case of solenoid variation parameters, which affect the performance of the solenoid-based polarization controller.…”

Controlling the polarization of the light output from single-mode fiber systems is very important for connecting it to polarization-dependent integrated optical circuits, while applications using a heterodyne detection system. Polarization controller using fiber squeezer is attractive for a low-loss, low-penalty coherent optical fiber trunk system. However, for polarization controllers using electromagnetic fiber squeezer, the stability problem due to the saturation of their magnetic circuit must be studied. In fact, in their conventional configuration, open-loop stability affects performance and limits applications. First at all, this effect has been analyzed and a feedback circuit with correctors has been proposed to improve stability performance. Then a simulation study is proposed to examine the influence of the system parameters on the corrector constants. The results of the simulation show that if the system parameters change the constants Kp, Ki and Kd of the PID corrector must be adjusted to keep an optimized dynamic response.

“…In electromechanical solenoids (EMS), also called electromagnetic devices (EMD), driven by a control solenoid, the armature is positioned by balancing the electromagnetic force against that of a return spring. They are relatively an inexpensive construction [1], have a simple design and control circuit, require little energy for control, are highly reliable [2], these electromagnetic actuators are used in wide range of modern industrial equipment such as digital actuator arrays [3], vehicle vibration control systems [4], gas valve [5], robotic manipulators [6], positioners [7], anti-braking systems [8], and polarization controllers where solenoids are used as mechanical actuator on the fiber to adjust the output light power [9]. In hydraulic systems, these electromagnetic actuators are commonly used in three basic categories to actuate hydraulic control valves directional-Journal homepage: http://ijece.iaescore.com Ì ISSN: 2088-8708 control, flow-control, and pressure-control.…”

As crucial parts of various engineering systems, solenoid valves (SVs) operated by electromagnetic solenoid (EMS) are of great importance and their failure may lead to cause unexpected casualties. This failure, characterized by a degradation of the performances of the SVs, could be due to a fluctuations in the EMS parameters. These fluctuations are essentially attributed to the changes in the spring constant, coefficient of friction, inductance, and the resistance of the coil. Preventive maintenance by controlling and monitoring these parameters is necessary to avoid eventual failure of these actuators. The authors propose a new methodology for the functional diagnosis of electromagnetic solenoids (EMS) used in hydraulic systems. The proposed method monitors online the electrical and mechanical parameters varying over time by using artificial neural networks algorithm coupled with an optical fiber polarization squeezer based on EMS for polarization scrambling. First, the MATLAB/Simulink model is proposed to analyze the effect of the parameters on the dynamic EMS model. The result of this simulation is used for training the neural network, then a simulation is proposed using the neural net fitting toolbox to determine the solenoid parameters (Resistance of the coil R, stiffness K and coefficient of friction B of the spring) from the coefficients of the transfer function, established from the model step response. Future work will include not only diagnosing failure modes, but also predicting the remaining life based on the results of monitoring.

Safety issue is great concern for rehabilitation robots that are expected to contribute to future aging society. Appropriate compliance is required for their joints. However, combination of servomotors and high-ratio gears, such as harmonic gears makes the joint of robots nonbackdrivable. The nonbackdrivability causes lack of adaptability and safety. On the other hand, Conventional direct-drive systems, including linear motors, are relatively big for such application. This paper presents development and analysis of compact high backdrivable direct-drive linear actuator. The motor consists of a helical structure stator and mover. The mover does not contact the stator and moves helically in the stator under a proper magnetic levitation control. Thus, the motor realizes direct drive motion without mechanical gears. Decoupling control is proposed and integrated with disturbance observer to achieve robustness against model uncertainties and input disturbance. The main contribution of this paper is to experimentally realize the direct-drive feature of the helical motor.
