ERROR COMPENSATION
Figure 8.3 Example: online error compensation
In this example the target position has been reached in time though the load on the motor occasionally got
too high. The closed loop error compensation had been able to make up leeway by executing dynamic error
correction parameters. The virtual actual position (grey) calculated by the ramp generator and the actual
position measured by the encoder (blue) merged at the end. Positioning has been carried out successfully.
