Control Performance Improvement of Hydro-Viscous Clutch Based on Fuzzy-PID Controller

open access: yesEnergies, 2021
As a rotational speed controller, a hydro-viscous clutch (HVC) is usually used in the constant pressure water supply system to maintain the needed water pressure constant.

Hybrid frequency control strategies based on hydro‐power, wind, and energy storage systems: Application to 100% renewable scenarios

open access: yesIET Renewable Power Generation, 2022
Over the last two decades, variable‐speed wind turbines (VSWTs) have gradually replaced conventional generation. However, the variable and stochastic nature of wind speed may lead to large frequency deviations, especially in isolated power systems with ...

Position control under simultaneous limited torque and speed of a torque-driven nonlinear rotational mechanism [PDF]

open access: yes, 2016
"This paper deals with shaft displacement regulation (position control) of a torque-driven nonlinear gravity unbalanced mechanism under both prescribed bounded torque and speed. This is a novel control objective formulation for mechanisms.

Cross-Saturation Effects in IPM Motors and Related Impact on Sensorless Control [PDF]

open access: yes, 2006
Permanent-magnet-assisted synchronous reluctance motors are well suited to zero-speed sensorless control because of their inherently salient behavior. However, the cross-saturation effect can lead to large errors on the position estimate, which is based ...

Position estimation delays in signal injection-based sensorless PMSM drives [PDF]

open access: yes, 2012
The causes of position estimation delays and their effects on the sensorless control of permanent magnet synchronous motor drives are investigated. The position of a permanent magnet synchronous machine is estimated via the injection of high frequency ...

Analysis of the influence of inverter PWM speed control methods on the operation of a BLDC motor [PDF]

open access: yesArchives of Electrical Engineering, 2018
An analysis of the influence of inverter PWM speed control methods on the operation of a brushless DC (BLDC) motor was carried out. Field-circuit models of the BLDC motor were developed taking into account rotational speed control by two classic methods:

Impact of cross-saturation in sensorless control of transverse-laminated synchronous reluctance motors [PDF]

open access: yes, 2006
Synchronous reluctance (SyR) motors are well suited to a zero-speed sensorless control, because of their inherently salient behavior. However, the cross-saturation effect can lead to large errors on the position estimate, which is based on the ...
