AUTOMATIC SELF-ADJUSTING MICROPROCESSOR-BASED SYSTEM FOR THERMAL MACHINE SHAFT RPM CONTROL Russian patent published in 2013 - IPC F02D41/26 

FIELD: engines and pumps.

SUBSTANCE: proposed system comprises thermal machine with load assembly, fuel hardware with fuel feed control element drive, shaft rpm transducer, fuel feed control element position transducer and thermal machine control unit. It comprises also the second driver, second comparator, first, second, third and fourth correctors, first and second multipliers, divider, adder and load assy power variator. Note here that first and second comparators, second driver, first and second multipliers, first, second, third and fourth correctors, divider and adder are incorporated with microprocessor controller including program with mathematical model of shaft rpm PI controller.

EFFECT: lower fuel consumption, longer life of thermal machine and decreased harmful emissions.
