Abstract (en)
[origin: WO2016079473A1] A method of controlling a motor in an electric supercharger when instructed to increase the speed of the motor to a target speed (2), the method comprising the steps of repeatedly:(i) calculating an adjusted target speed (13); (ii) determining the difference between the adjusted target speed (13) and the actual speed (4) of the motor; (iii) determining a torque set-point (10) for changing the speed of the motor from the actual speed (4) towards the adjusted target speed (13), and (iv) supplying electrical current to the motor dependent on said torque set point (10).The adjusted target speed (13) is calculated as a function of the time elapsed since the instruction to increase the speed, the function being such that, over a response time, the adjusted target speed (13) approaches the target speed (13).
