Abstract

PURPOSE:To correct a speed excellently as an operator intends, by avoiding the extreme speed change of an actuator when correcting track control manually in automatic operation. CONSTITUTION:For example, input equipment 13 in automatic operation is placed in correcting operation, switch 19 is opened with interruption signal S2 to cut off feedback signal w2, and consequently the output of adder 10 contains only open signal v2. Next, adder 22 adds open signal v2 and manual control signal x2 together to obtain input u2, consisting of v2 and x2, to flow control mechanism 4, and actuator 3 is brought under open control. The stability, therefore, improves remarkably. For the speed correcting operation, signal x2 by the correcting operation is added to signal v2, so that the change in operating speed of actuator 3 is corrected smoothly.
