Stationary analysis heater control

I have a model of an electrically powered radiant heater heating a part. My goal is to determine the heater power and thermal distribution on the part when the part reaches a desired average temperature setpoint. I am not particularly interested in transient behavior at this point.
I can get this to work using a smoothed step function to control the heater power as a function of a temperature probe, but only in a transient analysis run for long enough that everything comes to equilibrium. Trying to use this method with a stationary analysis results in convergence difficulties and unreliable heater power results (for instance, getting zero reported steady state heater power when the heater and part are both hot).
Is there a method to target/solve for heater power level to get my part to the temperature set point in a stationary (steady state) thermal analysis?
