DIGITAL INTEGRAL CONTROLLER Russian patent published in 2020 - IPC G05B11/01 H02P23/04 

FIELD: automatic controllers.

SUBSTANCE: invention relates to automatic regulators. Digital integral controller has six adders, six registers, an OR element, an AND-NOT element, three AND elements, a rectangular pulse generator and five monostable multivibrators. First and second inputs of the first adder are respectively the inputs of the reference and reference signals of the regulator. First and second inputs of the first AND element are the readiness inputs of the reference and feedback signals, respectively. Second input of the third adder is the input of the permissible increment of the floating constraint, the second input of the fourth adder is the input of the inverse value of the permissible increment of the floating constraint. Output of the fourth univibrator is the output of readiness of information at the output of the regulator, and the output of the second register – by the output of the regulator.

EFFECT: technical result consists in providing servo drive stable operation in all ranges of displacement and speed variation.
