Abstract
In general, the movement of DC servomotor in the range of lower speed is affected remarkably by the friction varied with angular position. By considering such friction, therefore, a new method of analog simulation, which is to simulate more exactly characteristics of the DC servomotor in the lower speed, may be obtained.
In this paper, on the basis of the above consideration, a method of analog simulation for DC servomotor in which the friction torque is dealt with as the sum of the angular velocity component and the angular position component is described.
Furthermore a comparison of the results of measurement and simulation for a servomotor is made. The various characteristics obtained from the measurement and the simulation give close agreement. The cause of the small difference between the results of the measurement and the simulation is briefly discussed.
