Abstract A model based controller is derived to stabilize a DC fed induction motor drive, with resonant input filter. By using a linearized feedback representation of the drive, it is shown how performance specifications can be translated into requirements on the input admittance of the voltage source inverter. This way the stabilization problem is reformulated as a loop-shaping problem, where the inverter input admittance should be given desired properties. In order to shape the inverter input admittance, the torque producing current reference is modified by the DC-link voltage via a stabilization controller. A general expression for this controller is derived in terms of the desired inverter input admittance. The analysis shows that stabilization may be needed also at operating points with zero power. Finally, an explicit expression for a stabilization controller that gives a good compromise between damping and disturbance rejection, but also is tractable from an implementation point of view, is proposed
