| Abstract |
Increasing demands on the efficiency and quality of
production have emphasized the need to develop better control
systems for electric drives. A simple PID controller does not
fulfill the performance requirements e.g. in motion control
applications. A feed-forward function in the controller increases
the bandwidth of the control loop. Load disturbances can be
approximated with a disturbance observer using input-output
measurements. In this study a structure of a disturbance
observer is described and its performance is analyzed with
simulations and measurements. |
