Attitude control method for propeller unmanned drone aircraft based on adaptive control

Abstract

The invention provides an attitude control method for a propeller unmanned drone aircraft based on adaptive control, and the method comprises the steps: 1, determining an unmanned plane linear mathematic model; 2, determining an unmanned plane linear mathematic reference model; 3, employing an adaptive control algorithm to calculate a control law upsilon of an unmanned plane linear control system. The method is used for designing an attitude controller of an unmanned plane, thereby enabling the actual control output of the system to quickly and accurately track the reference adaptive control of models. The method is high in resistance to external interference.

Description

technical field [0001] The invention discloses an attitude control method of a propeller unmanned target drone based on adaptive control, and belongs to the technical field of flight attitude control of small unmanned aerial vehicles. Background technique [0002] The propeller unmanned target drone is a commonly used small unmanned aerial vehicle. As a military training aircraft, the unmanned target drone provides imaginary targets for various weapons during military exercises or weapon test launches. The unmanned target drone is small in size, light in weight, has the characteristics of maneuverability and flexibility, and has broad development prospects in military applications. Attitude control is the most important part of the UAV control system. From the perspective of the structure of the flight control system, the attitude control loop is located in the outer loop of the damping loop and the inner loop of the track control. After the damping loop improves the maneu...

Problems solved by technology

At present, the design method of the controller generally adopts the classic PID control method. The PID control method can achieve a good control effect on the control of a simple system, but it will cause adjustment overshoot to the control effect of a complex system that is susceptible to external interference. and adjustment time can not be both good

[0004] The UAV itself is a high-order control object with complex dynamic characteristics with six degrees of freedom, and it is susceptible to external interference during flight, and due to the change of the center of gravity of the aircraft itself and the change of aerodynamic forces and moments with changes in the external environment, And, for this type of propeller unmanned target drone, it is also affected by the propeller reaction torque, which brings more uncertainties to the design of the attitude controller
