The invention discloses an unmanned aerial vehicle UAV control law parameter adjusting method, and aims at providing a parameter adjusting method which is large in parameter adjusting freedom degree,capable of effectively improving
system design efficiency and capable of saving cost. According to the technical scheme, the method comprises the steps that a
Matlab is used as a tool, and a general control console, a pneumatic coefficient module, an engine module, an undercarriage,
airplane wheels, a
brake model, a
pitch angle local controller at the
balance point of the unmanned aerial vehicle,a six-degree-of-freedom
airplane model and a general module
library of a
sensor model for building the control law of the unmanned aerial vehicle are generated; a
field bus control system FCS selectsa set
control mode to calculate a control law, an accelerator position instruction and a
rudder deviation instruction according to a control instruction given by the general console, ,,sends the flight state parameters of the unmanned aerial vehicle, and directly fits the obtained controller parameters at the characteristic points to obtain a function of the controller parameters about the heightH and the Mach number M and a parameter adjustment control law of a continuous change law of the controller parameters along with the parameter variables in the whole situation.
