摘要:

以高速微信号处理器ＴＭＳ３２０Ｃ３０为阵元机，研制了８阵元总线并行处理计算机系统，建立了涡轴发动机非线性仿真模型，仿真模型在并行处理机上并行计算实现实时。该实时仿真器通过输入输出接口与涡轴发动机的实际控制系统进行连接，组成涡轴发动机／控制系统半实物闭环系统，并进行了稳态和动态仿真。

Abstract:

A bus parallel processing computer system which contained eight processing units was made out.The TMS320C30 digital signal micro processor was chosen as the processing unit.A nonlinear real time simulation model was also provided,which was runned on the multi computer parallel processing system in order to obtain that the model could be calculated on line.The above simulator was connected with a real control system of a turboshaft engine throught the input and output interfaces of which close loop system of a turboshaft engine and control system was comprised.The semi physical simulation of the system at steady state and dynamic conditions was completed
