Filed: 1991-05-21
Abstract: PURPOSE:To shorten the response delay by using the arithmetic result of one side system as the initial value of the integrator of other side system when the arithmetic result is switched from one side system to other side system. CONSTITUTION:At the time of switching from an arithmetic result yA of a system A to an arithmetic result yB of a system B, the arithmetic result yA of the system A is used as the initial value of an integrator 9 of the system B. Thus, the arithmetic result yB of the system B is equal to an output result yA of the system A once at the time of switching, and subsequently, the recovery is performed to a stationary condition quickly. Then, even when the arithmetic result yB of the system B is not coincident from the arithmetic result yA of the system A, an output (y) outputted from a change-over switch 3 is continuously changed from the arithmetic result yA to the arithmetic result yB and the response delay is shortened based on the switching moving time.
