CONTROL OF A MOTOR IN AN ELECTRIC SUPERCHARGER

摘要

A control system (1) for controlling a motor in an electric supercharger, the system (1) comprises a memory module comprising an input variable cap behaviour (7) (for example a full-load curve), a processor arranged to apply the input variable cap behaviour (7) to impose an input variable cap (for example a torque cap) on the input variable (for example the torque) required to change the speed of the motor from the actual speed towards the target speed. The input variable cap in the input variable cap behaviour (7) preferably varies as a function of the speed of the motor. The input variable cap behaviour (7) is preferably selected from a plurality of different input variable cap behaviours (7), each being designed to achieve a different power consumption by the motor.
