If a control system has a dead time, it is difficult to control this system and even the application of the derivative control action is no longer effective for controlling the system with a pure dead time. The optimum nonlinear control for the system having a dead time can be obtained by switching the manipulated variable using four switching curves in the phase-plane, however the adoption of this method implies the increase of the complexities of the controller. On the other hand, if the control system has a dead time, the nearly optimum performance can be realized by simple relay control action. In this paper, the effectiveness of the simple relay control action for the system having a dead time is shown and the comparison between the response time of this system and that of other two nonlinear control systems is also presented.
