A servo system wherein an actuating signal obtained by the subtraction of a controlled variable delivered from a controlled system from a secondary command variable is applied to the controlled system, the actuating signal is added to the command to provide a secondary command variable, and the command is compared with the controlled variable in such a manner that when they are coincident with each other, the control is effected so as to change the secondary command variable to a predetermined value, thereby reducing both the transient error and the transient or settling time to a minimum and consequently decreasing the steady state error to a minimum. |
