A Torque Control Method Based on
IEEE Access, 2021 In traditional motor drive system, large volume electrolytic capacitors are utilized to buffer energy and stabilize the dc-link voltage. However, these capacitors affect the reliability of the drives and narrow the conduction angle of diode-rectifier. As

Current tracking control strategy for mine chain STATCOM
Gong-kuang zidonghua, 2019 In view of problems of strong interaction effect between STATCOM and power grid under weak power, the power voltage feed-forward control strategy is not effective in resisting power grid voltage distortion due to the delay, a current tracking control ...

On time-delayed and feed-forward transmission line models of the cochlea [PDF]
, 2010 The mammalian cochlea is a remarkable organ that is able to provide up to 60dB amplification of low amplitude sound with sharp tuning. It has been proposed that in order qualitatively to explain experimental data, models of the basilar membrane impedance

An ILC approach to feed-forward friction compensation
IFAC-PapersOnLine, 2020 Abstract An iterative, learning based, feed-forward method for compensation of friction in industrial robots is studied. The method is put into an ILC framework by using a two step procedure proposed in literature. The friction compensation method is based on a black-box friction model which is learned from operational data, and this can be seen as ...

Peak Current Control and Feed-Forward Compensation of a DAB Converter
IEEE Transactions on Industrial Electronics, 2020 The double active bridge (DAB) converter has been proposed in different applications due to its advantage of wide soft-switching range and power flow regulation capability. Applications like hybrid or electric vehicles and avionics systems require a fast dynamic response since the demanded power depends on the driving, which becomes an important factor

H-infinity control design with feed-forward compensator for hysteresis compensation in piezoelectric actuators [PDF]
Automatika : časopis za automatiku, mjerenje, elektroniku, računarstvo i komunikacije, 2016 Piezoelectric actuators, widely used in different micro/nanopositioning applications, generally exhibit nonlinear hysteresis characteristics. The compensation of hysteretic behavior of piezoelectric actuators is mandatory for precise micro/nanopositioning.

Research on Control Strategy in Giant Magnetostrictive Actuator Based on Lyapunov Stability
IEEE Access, 2019 The output characteristics of giant magnetostrictive actuator (GMA) are affected by many nonlinear factors, such as hysteresis, load, driving frequency and so on, which would lead to lower positioning precision, poorer repeatability, and even fall into ...
