This paper presents a novel approach to the inertia identification problem of mechatronic servo systems with limited strokes. In the proposed approach, the product of the integral of torque reference input and motor speed of mechatronic servo system in periodic motion is calculated. Then its time average over one period is used to calculate inertia. The(More)

In this article, a novel approach to the Coulomb friction identification problem of mechatronic servo systems with limited strokes is presented. The proposed approach utilizes two sinusoidal position reference inputs having the same amplitude to frequency ratio, and the first order time integral of torque reference inputs over multiple time intervals of the(More)

An algorithm to identify the inertia of mechatronic servo systems with infinitesimal motions is proposed. The proposed algorithm utilizes a position control with sinusoidal position reference input, and identifies total inertia of the motor and a mechanical load attached to the motor based on the amplitude of motor position at steady state. The proposed(More)
