Abstract

The present invention provides a semi-physical simulation method and device for an engine controller, wherein the method includes: a simulation main control module, an engine controller, and a thrust adjustment module; the execution of the simulation main control module includes: receiving an ignition signal, and The ignition signal is sent to the engine controller, so that the engine controller executes the preset control command; receives the variable thrust sensing signal generated when the thrust adjustment module executes the control command; Perform calculations to obtain simulated signals. By implementing the present invention, the simulation of the engine controller of the thrust-adjustable rocket can be completed, and the comprehensive performance of the engine controller can be tested before the actual ignition test run test by the simulation of the engine controller of the thrust-adjustable rocket. Eliminate basic test process errors and algorithm errors, reduce the number of test runs, and reduce the cost of test runs.

Description

technical field [0001] The invention relates to the field of liquid rocket engine control, in particular to a semi-physical simulation method and device for an engine controller. Background technique [0002] In recent years, with the development of commercial spaceflight, rocket recovery has become an important tool for low-cost access to space, such as liquid rocket engines. However, the thrust of existing liquid rocket engines cannot be adjusted, resulting in liquid rockets that cannot be recovered, and liquid rocket engines with adjustable thrust need to introduce a set of high-reliability electronic control systems, namely engine controllers. Before the engine controller is embedded in the rocket engine, a systematic, comprehensive, and reliable simulation test is required to ensure that after the rocket engine is connected, it can automatically handle various normal and abnormal conditions of test run test and flight test. [0003] In related technologies, multiple re...
