SYSTEM FOR REGULATION OF ROLLING MACHINES Russian patent published in 1998 - IPC

FIELD: automatic control, in particular, control of objects with several control inputs and one output parameter. SUBSTANCE: system has controlled object, three actuators, setter, four delay gates, two extrapolation units, first subtraction unit, serial circuit of first detector, comparison unit, low-pass filter, reverse object model without delay, first adder, third extrapolation unit and second subtraction unit. Outputs of first, second and third actuators are connected to first, second and third inputs of controlled object respectively. First output of controlled object is connected to input of first detector and output of regulation system. Output of first delay gate is connected to second input of second subtraction unit. Output of second delay gate is connected to first input of subtraction unit and through third delay gate to third input of second subtraction unit. Output of setter is connected to second input of comparison unit. Output of first adder is connected to input of first extrapolation unit and through second extrapolation unit to second input of first subtraction unit. EFFECT: increased precision of control. 1 dwg
