Abstract
As an important part of the air vehicle's control systems, the attitude control system has an important effect to the vehicle's performance. This paper introduces a new method of development of the vehicle's attitude control system by using virtual instrument. In the system, the air vehicle's attitude signals which come from SINS on two-axis turntable are received by RS232 in real-time, at the same time control algorithm in computer give the output control signals to Actuator via NI-DAQ . Air vehicle model and theoretic trajectory are given by MATLAB/Simulink which can be carried out in Lab VIEW. By using technology of virtual instrument, the parameters of the air vehicle can be show timely, control algorithm can be improved in real-time, and the performance of the control actuator can be tested all through. This system has hardware-in-loop which strengthens the reliability and authenticity.
