Variable stability control method based on characteristic structure configuration

Abstract

The invention relates to a variable stability control method based on characteristic structure configuration. By configuring the feedback gain and forward direction gain of a system, a linear time-invariant system is enabled to have given characteristic value and characteristic vector, variable stability control to a variable stability aircraft is achieved by using the characteristic structural vector of the linear time-invariant system, the variable stability control method is suitable for simulating a new generation warcraft to achieve the maneuver property of experiencing different crafts on one variable stability aircraft, and further the simulated training effect is further improved.

Description

technical field [0001] The invention relates to the technical field of variable stability aircraft control, in particular to a variable stability control method based on characteristic structure configuration. Background technique [0002] The variable stability aircraft (also known as the air flight simulator) can simulate the stability and handling characteristics of different aircraft through the fly-by-wire control system under the condition that the flight state remains unchanged; the variable stability aircraft can be used in flight quality analysis, control technology research, The aerial simulation of the new aircraft and pilot training have a wide range of uses. As for the trainer aircraft, if students can experience the handling characteristics of different aircraft on a stabilized aircraft, the training effect can be greatly improved.

Problems solved by technology

[0003] Foreign aviation developed countries began to develop variable stability technology very early, and this technology has been widely used in variable stability aircraft. During the "Ninth Five-Year Plan" period in China, the K-8V multi-axis variable stability aircraft was developed, which can achieve three-axis variable stability. However, due to the limited performance of the K-8 aircraft and the imperfection of domestic variable stability technology, it is no longer suitable for simulating a new generation of fighter jets. Therefore, it is necessary to improve and perfect the variable stability technology in order to seek breakthroughs in new fighter jets and new technologies.
