Real-Time Attitude Simulation of Aerocraft Using dSPACE Emulator and Three-Axis Turn Table
To solve the problem of ground simulation of aerocraft attitude in hardware-in-the-loop simulation (HILS), recurrence of aerocraft attitude is realized using dSPACE emulator and three-axis turn table. The hardware configuration and key technologies of control system are introduced. Construction and downloading of the dynamic model is done in dSPACE monitor computer, the model is calculated in dSPACE emulator. The communication between dSPACE and turn table is settled with serial-port of DS4201s card. The rotate motion of the inner middle and outer axis correspond to the three-channel motion of the aerocraft body. Simulation results indicate that dSPACE finish calculating complicated dynamic model, sending and receiving velocity data through serial-port is proper, bandwidth of turn table satisfies the need of simulation. Real rotating velocity of turn table is displayed using Controldesk tools, and fits well with the digital simulation data in pitching yawing and rolling directions, and the need for real-time attitude simulation in HILS is satisfied.
