Abstract: A control system for a machine may include an electronic controller configured to receive a sensor signal indicative of an operational parameter of the machine, and to output a control signal to an actuator to control an operational characteristic of the machine. The electronic controller may include a poles-zeros identification module, an onboard system identification module configured for online, real-time identification of one or more transfer functions that govern a dynamic relationship between one or more inputs and one or more outputs of at least one plant model, wherein the at least one plant model is representative of behaviors of the machine and simulates a dynamic influence of the operational parameter, and a comparator that determines the accuracy of a plant model.
