Abstract

The invention relates to an aircraft overload loop design method for providing damping by adopting angular acceleration and belongs to the technical field of aircraft control. According to the method,an angular accelerometer is adopted to measure the yaw angular acceleration of an aircraft to provide damping for an overload outer loop, then an accelerometer is adopted to measure the linear acceleration of the aircraft to obtain lateral overload; the lateral overload is compared with an expected overload instruction, and therefore, an overload error signal is obtained; integration is performedon the overload error signal twice, so that an overload error comprehensive integration signal can be formed, so that a conversion static error problem between the overload instruction and an attitude instruction can be eliminated; the nonlinear transformation signal of an aircraft attitude angular acceleration signal, the proportional signal of a yaw rate and the secondary nonlinear transformation signal of an aircraft angular speed signal are introduced to form the damping signal of the overload loop, and the damping signal is output to an attitude stabilization loop, so that the control objective of overload tracking can be realized. With the method adopted, the problems of static error and insufficient damping of traditional overload control can be solved.

Description

technical field [0001] The invention belongs to the field of aircraft control, and in particular relates to a control system design method for aircraft attitude stability and overload stability, mainly using a linear accelerometer and an angular accelerometer as measuring components to measure the aircraft's overload and attitude angular acceleration, thereby providing damping to increase the aircraft System stability. Background technique [0002] Although most of the current aircraft adopt the traditional attitude control system, it is more convenient to use overload control and proportional guidance matching for the guidance of the terminal unmanned aerial vehicle, especially for the unmanned aerial vehicles using proportional guidance. At the same time, for the UAVs for air defense interception, in order to increase their maneuverability and increase the probability of interception, most of them also use overload control. However, the overload control is also divided in...
