Zusammenfassung:In a feedback control circuit, a circuit maximizes or minimizes a controlled signal by incrementally varying the controlling signal in one sense, determining the direction of controlled signal change in response to such variation, and then incrementally varying the controlling signal in the same or the opposite sense in accordance with such direction. A condition of the system is that the controlled signal must reach a maximum or minimum in the range of the controlling signal. For illustration, the circuit is described in an analog-digital form applied to a wheel slip control of an electric locomotive to adjust the motor current to a maximum value to obtain the peak tractive effort that the rail conditions will permit.
