The Hardware-in-the-Loop Simulation on the Control System of a Small Launch Vehicle
Procedia Engineering, 2012Co-Authors: Huang Wen-bo, Zhang QiangAbstract:Abstract The Hardware-in-the-Loop Simulation plays an important role in aerocraft design. In Hardware-in-the-Loop Simulation on launch vehicle, some hardware components are connected to the Simulation loop and then work driven by data from the running computer which yield different operand quantities in different coordinate frames. According to the analysis on characteristic of the ballistics in the inertial launch reference frame, a Hardware-in-the-Loop Simulation system for a small launch vehicle containing IMU, rocket-borne computer and rudder is established. Simulation results indicate the control scheme is accurate, the algorithm of navigation, guidance and attitude control are valid, and the calculation reduction quantity benefited from using the data in the inertial launch reference frame rather than in launch reference is worked out.

A New Hardware-in-the-Loop Simulation Scheme of Inertial Navigation System
Computer Simulation, 2005Co-Authors: Li Xin-weiAbstract:Because only the three-axis angular motions can but the three-axis linear motions can't be emulated by three-axis revolving table, the inertial navigation system can't completely work in Hardware-in-the-Loop Simulation. A new Hardware-in-the-Loop Simulation scheme of inertial navigation system, which uses real data measured by accelerators and gyros, is put forward. The complete navigation computing is accomplished by external compensation of linear motions in the scheme. Not only the integrity of the inertial navigation system is guaranteed in Hardware-in-the-Loop Simulation, but also the transfer alignment can be completed in the scheme. The validity and correctness are verified by digital Simulation.
