Airplane Herbst maneuvering control method

Abstract

The invention provides an airplane Herbst maneuvering control method, and the method is based on a dynamic reverse idea. A designed controller comprises an outer ring flight path controller and an inner ring posture controller. The outer ring flight path controller calculates an attack angle instruction, a sideslip angle instruction, an instruction of a roll angle about the velocity vector and an engine thrust instruction for controlling the velocity of an airplane for achieving the set maneuvering light path. The inner ring posture controller controls the attack angle, the sideslip angle and the roll angle about the velocity vector through operating a pneumatic control plane of the airplane and a thrust vector. The method obtains an analytical expression of the outer ring flight path controller, wherein an attack angle instruction controller has an I controller form in a PID controller, and avoids the complex numerical calculation. Meanwhile, the method can adjust the solving precision of the control instruction, and is more suitable for the design of an airplane Herbst maneuvering controller in the engineering field.

Description

Technical field [0001] The invention belongs to the technical field of maneuver control for aerospace vehicles, and particularly relates to a Herbst maneuver control method for an aircraft. Background technique [0002] Aircraft with the ability to maneuver through stalls have an advantage in close combat. The Herbst post-stall maneuver was proposed by Dr. Wolfgang Herbst in the early 1980s. It integrates basic post-stall maneuvers such as the aircraft dynamically pulling up the angle of attack and entering the post-stall state, and rolling around the speed arrow at high angles of attack. It is an inspection aircraft The standard verification action for the maneuverability of the post-stall. In the Herbst maneuver, the aircraft makes a large jump from the normal flight state so that the angle of attack reaches and exceeds the stall angle of attack. With the decrease of the aircraft speed, the aircraft is quickly turned by manipulating the aircraft to roll around the speed vector...

Problems solved by technology

For the nonlinear implicit algebraic equations with time-varying parameters encountered in the design of the Herbst outer-ring track controller, previous scholars used classical methods such as Newton's method to solve them. The calculation efficiency is not high, and it is difficult to guarantee the solution accuracy. Take into account the two dimensions well
