Flight Reliability of Multi Rotor UAV Based on Genetic Algorithm
Abstract: The UAV system has
been widely applied in various military and civil fields. This technology mainly
is applied to radar positioning, wild fire management, agricultural monitoring,
environmentalmonitoring, aerial photography and search and rescue mission. It
conducts real-time monitoring andcontrol on the inclination angle, inclination
angle speed and accelerated speed of inclination angle basedon the flight
attitude control of the multi rotor UVA. Secondly, it controls the swing
deflection of rotor, motor speed, inclination angle control and speed based on
the optimal solution ability to overall search of the genetic algorithm to
achieve the real time optimization of parameters. Then, it establishes the
servo unit with direct torque current which will be combined with the sliding
mode controller to reconfigure the slidingmode variable structure controller
with direct torque to carry out control on the motor balance in advance. The
experiment results show that the servo unit with direct torque current together
with genetic algorithmrealizes the error correction of the hovering rotor of
UVA; during the dynamic control of the UAV fight, the gyroscope is sensitive to
the change of the aerial carrier attitude and then the correction to the drift
of gyroscope can be realized to provide stable reliability control for the
whole UAV flight.
