We take a look at a new solution that is said to overcome the traditional challenges of controlling in all four quadrants with an AC motor.

Abstract: This letter investigates real-time implementation of a finite-time control for permanent magnet synchronous motors in the presence of ... ensures a finite-time convergence of the speed state ...

Abstract: An electrical variable transmission (EVT ... the torque on both rotors of the EVT can be simultaneously controlled by using a field-oriented control (FOC) scheme. It describes an ...
