滑翔

The design method of fractional Controller for angle stability loop and mass center control loop of GREP was studied.The fractional PI~λD~μController and integral PID Controller were designed respectively for some type GREP.The simulation results show that the fractional PI~λD~μController designed by this method has its own features compared with PID Controller.
