Aircraft Thrust Scheme Optimization Hybrid Program Based on Simulink-M

针对Simulink循环和寻优操作复杂、执行效率低和M文件编程环境程序结构复杂、建模及修改比较困难的问题,提出了基于Simulink-M文件的混合编程方法,有效地提高了程序的执行效率.应用此方法编制了针对特定飞行器推力方案优化的仿真程序,对3种推力形式中可能出现的不同方案进行全局寻优,并对各方案进行对比,得到了针对不同推力形式的最优结果.仿真结果表明,混合编程方法具有较好的实用性.

Hybrid programming based on Simulink-M file,that can improve the program execution effectively,is proposed.The problems that it is hard to cycle and search in high efficiency in Simulink and that it is hard to build and modify the program model in M file are solved.By this method,simulation program for the optimization of specific aircraft thrust scheme is worked out.Global optimization for potential schemes in the three different thrusts is accomplished,and the optimized results for different thrusts obtained by comparison.It is indicated that the method has good practicality.
