  • Method and means for producing a control signal for process control including removable means for increasing gain as a time integral of error
    Patent number: 4008386
    Abstract: A removable control signal is provided which varies as the product of a gain constant times the control error and has means for increasing the gain constant as a time integral of the error. The integral is reset to zero, thus making the gain constant zero, when the error crosses zero to avoid an excessive build-up of the value of the control signal as when the error fails to promptly correct itself.
