Parallel Real-time Digital Simulation of The Attitude Motion of a Launch Vehicle
运载火箭姿态运动并行实时数字仿真

In this paper, the constructive techniques for parallel real-time simulation models of the atti-tude motion of a launch vehicle are consideied. First, the mathematical model is transformedfrom the usual system into one which is easy to parallelize. Secondly, the preprocessed numericalintegration methods are applied to the transformed system in order to decrease the amount ofwork per step and communication between processors, and the input correctors are adopted topreserve the dynamic accuracy of the original methods. Finally, a run-time model is establishedfor the real-time simulation model which is then distributed among the processors of the mul-tiprocessor system.
