In the previous paper, I had derived the block diagram and the transfer function of the S. F. Kraemer system. In this paper, I will study about the automatic speed control design of the concrete S. F. Kraemer system induction motor, which is based upon the transfer function derived in the former paper. For the synthesis of the transient performance of it, I have depended upon the frequency response method, and adopted the series compensation system as compensation one. The output voltage wave form of D. C. tacho-generator, which was used to detect the change of rotation, contained some ripple voltage wave form of very low frequency in it, and it acted to the system as noise. In order to avoid the influence of this very low frequency ripple voltage, I chose the lag network for the series compensating network. Therefore, the quickness of the transient response was more or less slower than the cases of the other series compensating network. But, the obtained performance was desirable enough to ordinary purpose except for the severe requirement.
