Abstract

The invention discloses a micro turbojet engine control system and a starting control method. The micro turbojet engine control system comprises an auxiliary controller, a main controller, a console controller and a measurement and control system. Wherein the auxiliary controller is installed in an engine shell, and starting motor driving, hot fire head driving, valve driving, vibration measurement, temperature measurement and rotating speed measurement are achieved; the main controller directly drives the oil pump, controls the auxiliary controller to realize a main control algorithm, and measures thrust through an engine pedestal; the console controller is used for giving action instructions of each actuating mechanism, giving signals of an accelerator push rod and acquiring feedback signals; the auxiliary controller, the main controller and the console controller are communicated through a bus; and the measurement and control system is connected to the main controller, so as to display parameters of the sensor, manually control the actuating mechanism and record test data. Starting and operation control over the micro turbojet engine is achieved through the control system, and the micro turbojet engine control system has the advantages of being simple in connection, high in control precision, flexible in combination, convenient to test and the like.

Description

technical field [0001] The invention relates to the technical field of avionics control. In particular, it relates to a micro-turbojet engine control system and a starting control method. Background technique [0002] Micro turbojet engine is a special kind of aero-engine, which has the characteristics of small size, light weight and large thrust-to-weight ratio. It has broad application prospects in military and civil fields. [0003] Micro-turbojet engines are widely used. In addition to being used as propulsion power units for small aircraft, such as unmanned aerial vehicles, missiles, etc., they can also be used as power generation power units with high power density to drive generators to form high-power power supply equipment. They are widely used in the power industry. In recent years, the distributed power system with micro-turbojet engine as the core has gradually attracted great attention. [0004] In terms of controller research, most micro-turbojet engines curr...
