Iterative identification of state-dependent disturbance torque for high-precision velocity control of servo motors
In the above mentioned paper,(1) a numerical example is given to show that the Nevanlinna-Pick interpolation formulas appearing in [1] and [2] are Incorrect. Bg comparing [2] with [3] we illustrate that the correct formulas are obtained by simply taking the transpose of the Pick matrix given in [1] and [2].
