COMBINED ROBUST CONTROL SYSTEM FOR NON-STATIONARY DYNAMIC OBJECTS Russian patent published in 2013 - IPC G05B13/02 

FIELD: physics.

SUBSTANCE: disclosed is a combined robust control system for non-stationary dynamic objects, having a coefficient unit, first, second and third adder units, a parallel compensator filter, first and second multipliers, a delay unit, a control object whose outputs are connected to corresponding inputs of the coefficient unit; inputs of the adder unit are connected to corresponding outputs of the coefficient unit; the output of the adder unit is connected to the input of the parallel compensator filter, the output of which is connected to both inputs of the first multiplier and the second input of the second multiplier, wherein the output of the first multiplier is connected to the first input of the second adder unit and the first input of the third adder unit; the output of the second adder unit is connected to the second input of the third adder unit and the input of the delay unit, the output of which is connected to the second input of the second adder unit; the first input of the second multiplier is connected to the output of the third adder unit; the output of the second multiplier is connected to the input of the control object.

EFFECT: providing dissipative stability of the investigated system for unstable objects with non-periodic external and parametric perturbations.
