Abstract

PURPOSE: To make it possible to bumplessly switch a PI controller having the two different control constants, in accordance with a control mode, by making an output of the controller of the unworking side perform tracking to an output of the controller of the working side at all times.
CONSTITUTION: The magnitude of control input signals 51a, 51b to each controller in both the A and B modes is made Δa, Δb, respectively. While the A mode is being selected, as for the control output signal 55, a control output signal 54a of the A system controller is selected, and its value V54a is provided as the expression I. In this case, (a) is a Laplacean. On the other hand, as far as the B system controller is concerned, since the contact 14b is closed, the operation amplifier 11b forms a circuit of time lag of the first order of the time constant Tb together with a capacitor 18b and resistors 19b, 20b, 22b. An input of this circuit consists of an output signal 52b of the linear amplifier 12b and a control output signal 54a of the A system, the value V53b of an output signal 53b of the operation amplifier 11b steadily becomes as the expression II. In the end, the value of a control output signal 54b of the B system controller becomes as the expression III by adding 52b and 54a, and the output signal 54b of the B system performs tracking to the output signal 54a of the A system.
