CONTROLLER Russian patent published in 2009 - IPC G05B11/32 

FIELD: physics; control.

SUBSTANCE: invention relates to a system for controlling output signal of a controlled object using feedback through several input control signals. Electronic control device 2 which is part of control system 1 regulates number of revolutions of the engine shaft NE during idling using the input signal for controlling ignition Us1-ig and the input signal for controlling intake Us1-ar. The electronic control device calculates the target number of revolutions NE-cmd in accordance with temperature of the engine coolant TW or similar, and determines the input signal for controlling ignition Us1-ig and input signal for controlling intake Us1-ar using several algorithms for controlling gliding mode with two degrees of freedom of the type of filter of the given target value, which jointly use one switching function such that, the number of revolutions of the engine shaft NE converges to the target number of revolutions NE-cmd.

EFFECT: possibility of increasing stability of control and accuracy of control when controlling output signal of a controlled object using feedback through several input control signals.
