Abstract
The present invention discloses a control system for an electric machine. In order to control the electric machine, predetermined frequency components are extracted from manipulated variables or measurement variables of the electric machine and are multiplied by a previously calculated control matrix. The control matrix can be calculated in advance here. Different control matrices can be formed in advance for different applications. As a result, simple efficient and robust control of the electric machine is possible, in particular for optimising and minimising harmonics.
