Abstract
An electronic control system () for a turbopropeller engine () having a gas turbine () and a propeller (), coupled to the gas turbine, the control system () having a propeller control unit () and a turbine control unit () to jointly control engine power output based on an input request (PLA), wherein the propeller control unit () has a first reference generator (), to determine a reference propeller speed (N) based on the input request (PLA), and a first regulator (), to regulate a propeller speed (N). The propeller control unit () has a reference correction stage () to apply a correction to the reference propeller speed (N) and generate thereby a corrected reference propeller speed (I), and the first regulator () regulates the propeller speed (N) based on the corrected reference propeller speed (I) to achieve optimized efficiency.
