Dependence of resistance on slip in an asynchronous motor.

Hello
How can I make the resistance and inductance depend on the slip in an asynchronous motor from the simscape electrical library?
I need these values to be a slip function

Hi,
For asynchronous machines, at each steady-state operation, the rotor resistance depends on the slip, i.e., Rr'/s, where Rr' is the rotor resistance (referred onto the stator side) corresponding to the standstill condition; s is the slip. The asynchronous machine model can reflect the above behavior at each steady-state operation. So there is no need to have a tunable rotor resistance depending on the slip in the model block parameters. A user only needs to specify the rotor resistance (referred onto the stator side) corresponding to the standstill condition. As for the rotor leakage inductance Llr’, it does not depend on the slip.
