A study on altitude control for the Small Unmanned Aerial Vehicles using the grey predictor-fuzzy PID

A novel method to control method of Small Unmanned Aerial Vehicles is presented in this paper. The method is based on the construction of the grey predictor-fuzzy PID controller. Firstly, the transfer function of the control is derived and the PID controller is constructed, then the fuzzy controller based on the error information of the control is established to realize the self-tuning of PID controller parameter, lastly, a grey prediction model is applied to calculate the data the sensor has acquired and forecast the which is the input value of the fuzzy PID. A simulation program established in MATLAB with aerosim toolbox verifies the validity of the method presented in this paper.
