Title:
CONTROLLER
Document Type and Number:
Japanese Patent JPS58139202
Kind Code:
A
Abstract:
PURPOSE:To attain stable and multiplex control with less dispersion, by providing circuit to the output sides of each control circuit and a feedback circuit, at a control device provided with plural control circuits and feedback circuits. CONSTITUTION:Outputs X1, X2, X3 of control circuits 11, 12, 13 are given from terminals A, B, C to a selection circuit 5, an intermediate value is selected and outputted from a terminal M and inputted to feedback circuits 41, 42, 43. The output from the feedback circuits 41, 42 43 is given to a selection circuit 6 from the terminals A, B, C, the intermediate value is selected and inputted to operation circuits 21, 22, 23 from the terminal M. The circuit 5, 6 consist of diodes, resistors, a positive power supply and a negative power supply and selects an output decided by the majority to inputs or the intermediate value. But the output value to be selected can be a maximum or a minimum value.
