Embodiment Construction

[0029] like figure 1 Shown is the UAV attitude control filter unit and method principle diagram of the present invention, the filter unit of the present invention includes a UAV attitude control mathematical model, an anti-interference filter and an optimal controller; the anti-interference of the present invention The filtering method first establishes a mathematical model of UAV attitude considering various disturbance moments and noises, and uses its output as the input of the designed anti-jamming filter. The estimated value of the state variables in the mathematical model of UAV attitude and the mathematical model of external disturbance The estimated value of the model state variables is sent to the designed optimal controller, and the output of the optimal controller is turned on to the anti-jamming filter and the mathematical model of the UAV attitude control loop for feedback control.

[0030] like figure 2 As shown, the UAV attitude control anti-interference filter...

Abstract

The invention discloses an unmanned plane attitude control filtering unit and method, and relates to a design for an anti-interference filtering method for unmanned plane attitude control. The invention aims at multi-source interference of an unmanned plane, such as atmosphere turbulence force moment, execution mechanism noise, measurement noise, and model nondeterminacy. The method comprises the steps: firstly building an unmanned plane attitude mathematic model comprising the multi-source interference; secondly building a multi-source interference moment mathematic model; thirdly designing an anti-interference filter for the unmanned plane attitude; finally designing an optimal controller, and carrying out feedback control. The method is strong in anti-interference capability, is high in control precision, and can be used for unmanned plane attitude control.

Description

technical field [0001] The invention relates to an unmanned aerial vehicle attitude control filtering unit and method, which can be applied to the attitude control of unmanned aerial vehicles containing multi-source interference such as atmospheric turbulence moment, actuator noise, measurement noise and model uncertainty. Background technique [0002] The small unmanned rotorcraft has the characteristics of vertical take-off and landing, hovering, etc., and can perform tasks in narrow spaces such as urban streets, and has a wide range of application prospects. With the expansion of the application field, the demand for the intelligence of small unmanned rotorcraft is also increasing, and the fully autonomous and highly intelligent small unmanned rotorcraft has become a research hotspot. As a complex multiple-input and multiple-output control system, small unmanned rotorcraft has the characteristics of strong coupling, nonlinearity, and high control difficulty, and its dynam...
