Recently, the model based control has been successful applied for motion control applications. It improves better performance than a classic linear control. However, a model base control needs to know some parameters for exact estimations, here a load torque and stator resistance. In this paper, it presents three-observers for a differential flatness model based control approach for a DC permanent magnet motor drive. Observer I is based on the well-known Luenberger estimation (linear approach); Observer II is based on the non-linear approach which guarantees the asymptotical stability; and Obserser III is also based on the non-linear approach which guarantees the exponential stability. To validate the proposed methods, a prototype DC servomotor drive (GEC Alsthom: 2-kW, 2400 rpm) is realized in the laboratory. Simulation and experimental results demonstrate system performance.
