1. A method for determining fixed parameters of a match network model, comprising: measuring an efficiency of an impedance matching network; applying an input power at an input of a match network model to calculate a predicted output power at an output of the match network model when the match network model is assigned a fixed inductance, a fixed capacitance, and a fixed resistance; calculating a predicted efficiency of the impedance matching model from the predicted output power and the input power; determining whether the predicted efficiency is within a predetermined limit from the measured efficiency; and assigning the fixed inductance, the fixed capacitance, and the fixed resistance to the match network model after determining that the predicted efficiency is within the predetermined limit from the measured efficiency.
