This paper proposes an identification method for mechanical parameters based on position control. To improve motion control performance, the moment of inertia and friction components must be considered. Based on mechanical equations, the proposed method estimates the moment of inertia, viscous friction coefficient, and Coulomb friction in the off-line state. Mechanical parameters are obtained from the integral values for the products of the torque, speed, and position using the 90° phase relationship between acceleration and velocity. Simulation and experimental results demonstrate the validity and accuracy of the proposed method. Since its implementation is simple, this method can be applied easily to industry.
