Abstract-The DC motor of Control system is a control algorithm for most PID. In this paper, a kind of intelligent ultra short feedback endocrine controller is designed, which is based on the mechanism of hormone secretion regulation, and is applied to the control of DC motor. The endocrine controller includes the traditional control unit, the ultra short feedback unit and so on. First the control signal of the endocrine controller is operated by the traditional control unit. Then the control signal is processed by the ultra short feedback unit according to the regulation of hormone. In the end, the output signal of the ultra short feedback unit and the output signal of the traditional control unit are combined and output, thus a nonlinear control algorithm is formed. The new control algorithm is applied to the DC servo motor model and the three -level water tank model. This paper conducts a simulation comparison through programming. The simulation results show that the controller has good stability, fast performance and anti disturbance ability with the traditional PID control.
