Abstract
A method and apparatus for use with a plant drive system that receives a reference command signal and generates a torque command to drive a plant, the method for estimating plant inertia and comprising the steps of providing a reference model that models the plant, the model receiving the reference command signal and generating a model output signal as a function thereof, identifying a plant output signal, mathematically combining the reference command signal and the plant output signal to generate a first error value, mathematically combining the plant output signal and the model output signal to generate a second error value, mathematically combining the first and second error values to generate an inertia estimate value and using the inertia estimate value to modify the torque command thereby providing a modified torque command signal to drive the plant.
