The Ameliorative Design Of Integrated Flight/propulsion Control Computer And The Optimization Of Control Parameter

Integrated flight/propulsion control (IFPC) optimization computer is used to optimize the performance of the aero-engine, which can improve the performance of the propulsion system significantly by utilizing the real-time information of the aircraft and engine to trim the engine control inputs. This paper studies the program and optimization algorithm of IFPC optimization computer, and the program is modified to make it modularization. According to the requirement of the project, serial communication module is appended to optimization computer which is based on TMS320VC33DSP. Hardware architecture and software realization of serial communication is discussed and implemented. The result of Hardware-in-Loop simulation indicates that serial communication can satisfy the optimization computer requirements. In order to keep the optimization computer in the smallest size, it is implemented based on the highly integrated TMS320F2812DSP. To resolve the real-time problem of the optimization computer, the design of the optimization computer based on Double-DSP is introduced. This new design lays a good foundation for further development of the optimization computer. Finally, optimizing the parameters of aero-engine PID controller by Genetic Algorithms (GAs), which enriches the IFPC connotation, is introduced. The results of the simulation indicate that this optimization method can improve the performance of the PID controller and the dynamic behavior of the aero-engine control system.
