Title:
CONTROL DEVICE FOR SYSTEM, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2022/270268
Kind Code:
A1
Abstract:
This control device is applied to a system comprising a rotating electrical machine (20) including a rotor (22) and a stator winding (21), an electricity storage unit (31), and an inverter (30) including higher and lower arm switches (SWH, SWL). The control device comprises: a command calculating unit (55) for calculating a command value, which is either a command torque (Trq*) or a command rotational speed (Nm*) of the rotating electrical machine; and a rotating electrical machine control unit (37) for performing switching control of the higher and lower arm switches on the basis of the calculated command value in order to control the torque of the rotating electrical machine to the command torque. The rotating electrical machine control unit calculates an upper limit rotational speed (Nmlim) of the rotor at which the rotating electrical machine and the inverter do not overheat, on the basis of the drive state of the system. The command calculating unit performs protection processing to keep the rotational speed of the rotor equal to or less than the calculated upper limit rotational speed.
