Abstract

The invention relates to the technical field of aviation, in particular to a method for controlling the adjustment starting angle of a swash plate through a nonlinear control law. The preset control law is set through the computer, the inclination angle of the inclined plate is adjusted based on the preset control law through the adjusting assembly, according to the method, the preset control law is processed through the computer in a non-linear mode, the adjusting assembly controls the angle of the inclined plate according to the preset control law, and the control precision and the response speed of the inclined plate in the air inlet channel can be improved; the problem that the adjustment starting angle of an inclined plate is too small due to the fact that the static supercharging ratio of an engine is too large is solved.

Description

technical field [0001] The invention relates to the field of aviation technology, in particular to a method for controlling the starting and adjusting angle of a swash plate by using a nonlinear control law. Background technique [0002] The aircraft intake swash plate adjustment system is an analog automatic control system, which consists of two identical and basically independent systems on the left and right. It receives the M≥1.4 signal from the atmospheric data computer and adjusts it according to the static pressure ratio of the engine compressor. Corner of the inclined plate. In the system design stage, the engine and aerodynamics majors determine the system control law based on the theoretical characteristics of the engine static boost ratio and the characteristics of the intake port, after wind tunnel test and flight test verification. During the long-term use of the aircraft in the field, the engine has undergone many overhauls and parameter adjustments, and its s...
