摘　　要：在基于DSP平台的某型航空涡扇发动机综合电子调节器的数字化研究中,提出了一种改进遗传算法,并将其应用于数字PID控制器的参数整定过程中。仿真结果表明,该改进遗传算法相比于基本遗传算法及常规PID参数整定方法,控制器动态性能更为优越,可调整性更强。In the research of a digital controller of a turbofan engine based on DSP platform, an improved genetic algorithm was applied to parameters＇ tuning of digital PID controller. According to the result of the simulation, this algorithm was superior to basic genetic algorithm and some other tuning method of PID parameters. The controller based on the improved genetic algorithm had an excellent dynamic performance, and its performance was adjustable in some range.
