ABSTRACT:
A method and apparatus for estimating a system inertia and a load torque in a motor controller, the method comprising the steps of providing an acceleration command signal, determining a motor position, using the motor position to generate an acceleration feedback signal, mathematically combining the acceleration feedback signal and a load torque signal to generate a system inertia estimate, mathematically combining the system inertia estimate and the acceleration command signal to generate a motor torque signal, mathematically combining the system inertia estimate and the acceleration feedback signal to generate an inertia torque and mathematically combining the inertia torque and the motor torque signal to generate the load torque estimate.
