Engine environment self-adaptive control method and device, controller and flight system

Abstract

The invention relates to an engine environment self-adaptive control method and device, a controller and a flight system. The engine environment self-adaptive control method comprises the steps that the physical rotating speed and environment parameters of an engine are obtained in real time; a transformation coefficient is determined according to the environmental parameters; according to the transformation coefficient, the physical rotating speed is converted, and the fuel quantity in the actual working environment is determined through the converted rotating speed; and an oil pump is controlled to operate according to the fuel quantity in the actual working environment. According to the control method, environment self-adaptive control can be carried out on the engine under different weather conditions and different flight conditions, and the control method is low in calculation complexity, high in calculation speed and capable of meeting the real-time updating calculation requirement of embedded calculation.

Description

technical field [0001] The invention relates to the technical field of engine control, in particular to an engine environment adaptive control method, device, controller and flight system. Background technique [0002] As a power generating device, the engine's operating performance is often affected by the environment. For example, turbojet engines are usually used as power components for high-speed aircraft. Due to differences in ground climate conditions and flight conditions (such as flight altitude and flight speed), the performance of the engine will change, and a set of fixed control parameters cannot be changed. The performance control requirements of the engine are met under the environmental conditions. Although the engine environment adaptive control method has been proposed in the prior art, the existing control method has high computational complexity and slow speed, and cannot meet the real-time update calculation requirements of embedded computing. Therefore,...

For example, turbojet engines are usually used as power components for high-speed aircraft. Due to differences in ground climate conditions and flight conditions (such as flight altitude and flight speed), the performance of the engine will change, and a set of fixed control parameters cannot be changed. Meet engine performance control requirements under ambient conditions

Although the engine environment adaptive control method has been proposed in the prior art, the existing control method has high computational complexity and slow speed, and cannot meet the real-time update calculation requirements of embedded computing. Therefore, we propose a turbojet engine environment adaptive control method. The control method realizes the environmental adaptive control of the turbojet engine under different climatic conditions and different flight conditions
