- Page 2 “Plant” and “Controller”. The plant contains the drive system and the controller employs a vector control scheme. These subsystems can then be independently built on the PLECS RT Box either for Hardware-in-the-loop (HIL) testing of an external controller, or for rapid control prototyping (RCP).
