AUTOMATIC CONTROL SYSTEM OF GAS-TURBINE ENGINE ROTOR ROTATION FREQUENCY Russian patent published in 2011 - IPC F02C9/28 

FIELD: engines and pumps.

SUBSTANCE: this system, minimum signal selector output of which is connected to maximum signal selector second input, and isodromic regulator output is connected to executive device input, additionally includes controlled integrating unit, the input of which is connected to maximum signal selector output and the output is connected to isodromic regulator input, first logic device, the inputs of which are connected to minimum signal selector inputs, and output is connected to deduction element first input, second logic device, the inputs of which are connected to maximum signal selector inputs, and the output is connected to deduction element second input. The output of deduction element is connected to controlled integrator reset input and through first multiplier to controlled integrator initial value input. Note that maximum signal selector output is connected to first multiplier second input.

EFFECT: increase of system accuracy in changing speed of rotor rotation frequency by astatism input to control channels of acceleration and reset, thus improving GTE dynamic characteristics of time and decreasing static accuracy of control program realisation, this results in GTE accelerating capacity improvement and increase of its traction during acceleration mode.
