Summary

In this paper, the resonant compressor is studied and one new method for modeling using the gas pressure force's effects is presented. The gas pressure force is nonlinear and variable throughout the operation. Therefore, it is a very difficult task to calculate the resonance frequency with the necessary accuracy to optimize the compressor efficiency. Thus, the design of a high performance controller for linear compressor drive presents a challenge since the system is highly nonlinear. This new method proposes to deal with this problem through linearization of the gas pressure force. This new approach is based on the effects that this force causes in the compressor operation. From the use of this approach, it is possible to model and to analyze the compressor's behavior as a linear time varying system.
