The digital low-dropout (LDO) linear regulator is one of the latest innovations in the power industry, bringing telemetry and ...

This paper proposes a feedback control method for a linear resonant actuator (LRA), in which an external load estimated from two signals of the back-EMF is used as a target voltage in PID control.

Electric actuator is very important in industrial control field. Linear electric actuator is widely used in linear motion of valve switch or modulating control.
