1. A method of identifying a system, the method using a controller, comprising: calculating an estimated value of at least one parameter in a second-order model of the system; calculating at least one parameter in a first-order model of the system from at least one second-order model parameter using a transformation function based on a magnitude and phase of the second-order model at a natural frequency for the second-order model, wherein said calculating is performed using the controller; providing the at least one first-order model parameter to a computing device; and using the computing device and the at least one first-order model parameter to perform at least one of pre-tuning a feedback controller, configuring the feedback controller, and reconfiguring the feedback controller.
