In this paper, the fundamental principle and the design method of an optimalizing controller with dynamic hunting is explained in accordance withthe control theory. This controller can be used in process control system. In this con-trol system, there are large inertial and other dynamic effects. If the output lineargroup of the system is approximately 6 【pressed in a first-order system with largetime constant T or time dely τ, which can be written as transfer function K/(1+TS) or Ke~(?) (1+TS). Moreover, relation between input drive reversal of logic cir-cuit and dynamic output of the system is discussed in detail. The calculating for-mulas for the drive reversal of logic circuit are given to the different transferfunction and they are proved correctly by tests. In accordance with the layout men-tioned above a controller and a model of system has been designed and made out. Meantime, some special tests have been carried on and the results showed that theperformance of the controller satisfied the chnical requirments in design and it may search the optimum point rapidly and keep the system operates near the point.
