Constant vertical wind disturbance is a kind of important disturbance form. This form will bring big effect on keeping and controlling aero attitude angle and altitude. Based on established aero sport mathematics models with constant vertical wind disturbance, the structure principle diagram of aero angular displacement control system is founded. Based on MATLAB, simulation researches were emphases done on performance influence of aero angular displacement control system by different disturbance wind speed and disturbance time length. Simulation results show: aerocraft control system performance is greater impacted on constant vertical wind disturbance.
