Abstract: | Research on the design of acceleration controller using N-dot method is made for a two-spool civil turbofan engine. Based
on the PI controller, an N-dot design method which could fulfill the requirements was given, and a constrained nonlinear optimization
problem was proposed to obtain the PI parameters using pattern search algorithm. Then a closed-loop of a turbofan engine control with
setpoint controller and acceleration controller both was constructed for acceleration simulation. The results show that the acceleration
controller works well in an acceleration process and is of value for engineering application. |
