| 摘要: |
| 对于航空发动机这样复杂的系统,经典的定常算法难以对其实现良好控制。遗传算法具有良好的寻优特性,操作方便、速度快,不仅适用于单目标寻优,也适用于多目标寻优。遗传算法可以根据不同的控制系统,针对一个或多个目标,均能在规定的范围内寻找到合适参数。文中采用遗传算法实现了对PID参数的最佳整定。最后,通过数字仿真证明了其在航空发动机控制系统中应用的可能性。 |

| Abstract: |
| Due to its simplicity,utility and easy application,PID controller is used widely in classical automation systems.However,the performance of the PID controller cannot satisfy some systems which are complicated and nonlinear such as aircraft engines.This problem can be solved by the theory which is based on the genetic algorithms control theory.In this paper,the integrated flight/propulsion control system of a new fighter and its new turbofan engine are studied.The Genetic Algorithms and PID control were combined in this paper which were used to revise the parameter of PID.Finally,the simulation results indicate that the designed integrated controller has good performances. |
