Trajectory Guidance Law for MAV Based on MEMS Sensor/GPS

This paper studies a new trajectory guidance logic system for Bank-To-Turn fixed-wing (BTT) micro air vehicle (MAV) based on MEMS sensor / GPS , and introduce the method of estimating the navigation information from MEMS sensors and GPS. a nonlinear guided logic based on literature is utilized to get the desired roll angle , and a total energy controller is utilized in the longitudinal loop. Based on the kinematic model of the coordinated turning of MAV, the system can ensure that the aircraft stably track a flight plan segment. Flight tests on MAV prove the feasibility of the trajectory guidance logic system.
