Abstract:

To solve the problem of instability due to low measuring precision of sensor during micro unmanned aerial vehicle (MUAV) fixeddestination flight, a new control method is designed in this article with which flat flight is guaranteed by controlling navigation gyroscope angular rate on the transverse and lateral side while flight height is overloadcontrolled on the longitudinal side. Based above, a control method of fourpoint pressing line navigation is designed and the control stability on the transverse and lateral side is validated by the flight test. Experimental results show that these navigation and control methods could meet the requirements of fixedpoint and fixedcourse flight of MUAV with lowprecision silicon micro electromechanical systems (MEMS) measuring devices.
