ON INCREASE OF SPEED OPERATION OF CERTAIN SYSTEMS OF AUTOMATIC CONTROL,

Abstract

Optimal transients are considered in automatic systems where the principal control signal depends on the deviation of the controlled variable from its set value. The optimal transient process consists of acceleration and deceleration, both having a constant maximum value. The angular velocity linearly depends on time. The shortest transient process requires the functioning of a negative feedback and a time-proportional positive feedback. The second derivative of speed is selected as a control input that can ensure the speed-time linear relation. A negative feedback proportional to the error-signal first derivative is suggested for changing the sign of the control input. Restricting the error signal is proposed to ensure minimum duration of the control process for different initial errors (deviations). The above ideas are illustrated by an example of an automatic vector-measuring device. Shapes of control-signal curves are shown and explained.
