Abstract
PURPOSE: To enable to change the limit value of output of the main adjuster in correspondence to the limit value command signal, by applying the limit command signal having the amplitude corresponding to the input of the main adjuster to the limiter from the limit value generator.
CONSTITUTION: In the limiter used for the automatic control system, the limiters 15 and 16 limiting the output of the adjuster 1 to a given value are provided between the output terminal 4 and the input terminal 2 of the main adjuster 1 to the input signal to the adjuster 1. The limit value generator 17, 18 consisting of the amplifiers 19, 20, integration capacitors 21, 22 and resistors 23, 24, are provided, and the limit value command signal having the amplitude corresponding to the input of the adjuster 1 is fed to the limiters 15, 16. Thus, in response to the limit value command signal, the limit value of the output of the adjuster 1 can be changed.
