Abstract

The invention discloses a control method and a controller based on robust servo control and model adaptive control and belongs to the unmanned aerial vehicle control technology field. The method comprises the following steps of S101, acquiring control input of a system; S102, determining a structure of an adaptive controller; and S103, determining a mathematic model of an aircraft linear system. In the step of S103, introduced disturbance and uncertainty factors include rudder surface efficiency of an aircraft, matching disturbance, and mismatched wind disturbance. The method and the controller have advantages that a response is fast, the method and the controller have an inhibiting effect on various uncertainty interference types, and a steady-state response index, and transient responseperformance of a system can be ensured; and through a robust servo combination method, robustness of the system to a disturbance signal is increased and a dynamic response capability is improved.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicle control, in particular to a control method and a controller based on robust servo control and model adaptive control. Background technique [0002] UAV anti-airflow disturbance refers to the aircraft disturbance caused by encountering turbulence during flight, or encountering turbulence and ship wake disturbance during landing. In terms of the design of the anti-disturbance controller of UAV, looking at the research plans of domestic scholars, some scholars use the multivariable frequency domain algorithm based on LQG / LTR to verify the design of their longitudinal autonomous landing control system. The control method has strong robustness; some scholars use the classic PID to land on the land-based simulated aircraft carrier, and introduce the optical guidance method to improve the trajectory control accuracy. Through the actual flight, the requirements of the trajectory control ac...
