Abstract：The opening and closing spherical four axis remote control aircraft is a new type of UAV ,the flight naviga-tion control is key to ensure the aircraft attitude stabilization ,the traditional method uses static neuron control method , which can lead to small disturbances ,poor flight performance of aircraft stability is not good .A new navigation control algo-rithm is proposed based on variable structure fuzzy PID neural network .The coordinate system structure is described and the remote control dynamics analysis of aircraft is taken ,variable structure PID neural network control and Lyapunov small dis-turbance suppression method are used for improvement of navigation control algorithm .Simulation results show that the con-trol algorithm for opening and closing type spherical four axis remote control has good performance ,attitude angle can fast track to set the reference value ,attitude control error converges to zero in a relatively short period ,and it can avoid the im-balance of flight attitude ,it shows good control performance .
