Abstract

PURPOSE:To ensure the bumpless switch with high accuracy among plural controllers by converting the output of an AND circuit into the voltage value and supplying this voltage value to the controller of each system as a setting increase or decrease command. CONSTITUTION:The ANDs are calculated by AND circuits 16a-16d between a setting increase command given from a manual/automatic switch 3 and the high frequency pulses received from pulse generators 15a and 15b. Then the high frequency pulses are produced in proportion to the lengths of operation pulses 4a, 4b, 5a and 5b for a setting increase or decrease command. The pulse/ voltage converting circuits 17a and 17b converts these pulses into the analog voltage signals in response to the number of said pulses and decide the analog set value. Therefore the same control signal is obtained between A controller 8a and B controller 8b from the difference between said analog set value and a feedback signal 14. Thus the bumpless switch is possible with high accuracy between both controllers 8a and 8b.
