In this paper, a low sensitive position control system using a DC series servo motor driven by a chopper is presented. The digital simulation is employed for the design of this system in order to take account of non-linearity of the motor. The simulated responses are compared with the experimental ones. The low sensitivity is verified for the inertia load about ten times as large as that of the motor itself. The responses of duty cycle and driving electric energy for the specification are also presented. As a result, it becomes clear that this system is of much practical use, because the driving apparatus of this system is small and light comparing with the DC amplifier.
