“…PMSMs are classified as surface-mounted permanent magnet synchronous motor (SPMSM) and interior permanent magnet synchronous motor (IPMSM) according to the location of the PM. In particular, SPMSM is used in various applications owing to its low cogging torque and torque ripple [1,2]. However, cogging torque and torque ripple of motors increase due to rotor eccentricity.…”

Static eccentricity (SE) is frequently generated by manufacturing processes. As the nonuniformity of the air-gap length is caused by the SE, the torque ripple and cogging torque increase in the motor. This study analyzes the distorted back electromotive force (EMF) and cogging torque due to SE. Further, a motor design considering SE is performed for stable back EMF and low cogging torque. First, the SE was diagnosed and analyzed using the back EMF and cogging torque measured from the test results of the base model. In addition, the rotor position was calculated using the unbalanced back EMF due to the SE. The calculated rotor position is used when analyzing phenomena due to SE and applied to robust design. Subsequently, robust design optimization was performed to improve the unbalanced back EMF and cogging torque due to SE. Using finite element analysis (FEA) considering SE, the shape of the stator was designed based on the base model. The estimated rotor position from the base model was applied to the optimum model to confirm its robustness from SE’s effects. Finally, the base and optimum models were compared through the test results.

This study proposes an optimal design approach for an inverter-fed permanent magnet synchronous motor (PMSM) considering the variation in motor control parameters and input voltage (inverter output voltage), which vary with respect to the temperature and loading conditions, in an integrated brake system. In an integrated brake system, a quick response to load changes is crucial. Therefore, in this study, to consider the fluctuation in control variables and input voltage, the motor control parameters and input voltage were first calculated according to the operating temperature and loading condition. Subsequently, based on the calculated conditions and the approximated motor input voltage and control parameters, the objective functions corresponding to motor characteristics in transient and steady states were formulated using design-of-experiment (DOE), the moving least square method (MLSM), and the finite element method (FEM). Finally, the optimal design was performed using the genetic algorithm (GA). The validity of the proposed optimal design approach was verified by comparing its optimization results with the FEM analysis results. Thus, it was confirmed that a motor can be designed for an integrated brake system by considering the motor control parameters and motor input voltage, which vary with the driving conditions.

“…However, HSV encounters limitations such as restricted flux and the inability to produce continuous proportional flow [15,16]. Although adjusting the PWM signal's duty cycle can regulate the average flow over time [17], challenges like vibration, noise, and cavitation in water-based environments due to high-frequency switching persist [18][19][20].…”

Most mining hydraulic systems use water-based emulsions as the transmission medium. However, the low viscosity of water-based fluids causes leakage, making proportional flow control in water hydraulic systems challenging and preventing precise positioning of hydraulic cylinders. To achieve continuous flow control in water-based fluids, this research proposes a novel backstepping adaptive controller integrated with an extended sliding mode observer (ESMO). By using additional pressure sensors, continuous proportional control of the output flow of a two-stage high-speed on/off valve (TSHSV) can be realized. The ESMO estimates the valve spool position and unmodeled disturbances based on the current in the coil winding, and system output flow is derived from the spool position. An adaptive controller adjusts the spool position to control the entire system’s flow output, achieving proportional flow control. Simulation and experimental results validate the control accuracy of the system. The results show that the system’s performance surpasses that of proportional valves in many respects.
