Abstract
An experimental study of an observer-based closed-loop speed control scheme sensitivity to load torque disturbances, drive parameter variations, and observer pole location is analyzed theoretically and verified experimentally. These results demonstrate the observer-controller separation principle as well. The effect of observer design on estimation convergence from zero initial conditions is shown. The effectiveness of computing the position of the shaft from the observed speed is also tested by comparing the computed signal with the output of a shaft position sensor.<>
