A Study of the Manual Control System

Wada Tsutomu

An analysis is attempted of the human operator's responses to the sinusoidal input and the random input. The human operator's characteristics in the closed loop system are represented by the Bode diagram. This diagram shows that the human operator's response to the random input containing only those frequency components lower than 4 rad/s is almost in accordance with his response to the siunsoidal input of the same frequency range.
