Latest Patents

Hamid R. Sadeghpour holds a patent for a "Closed loop control system and method using back EMF estimator." This feedback control system utilizes estimated back electromotive force (EMF) from a controlled actuator to provide feedback into the control system, thereby improving actuator control. The system estimates back EMF from the current through the actuator and the voltage across it. The estimated back EMF signal is integrated into the control system, serving as a rate term. In the preferred embodiment, this back EMF signal is used alongside an actuator position signal, which is also fed back into the control system. A complementary filter conditions both the rate and position signals for enhanced performance. This invention is particularly suited for controlling linear actuators that do not provide conventional rate feedback signals.
