An Autopilot is certainly one of the most important parts of flying objects which creates stability and
achievement to appropriate operation in performing instructions of guidance part. The purpose of this
study is to use one of the dynamic models for actuator, in order to evaluate the performance of autopilot
system. Moreover, at last by using Model Reference Adaptive Control (MRAC), the system will approach
suitable output and have the lowest number of errors. The system is modelled by using
MATLAB/SIMULINK and assessed by various amounts of control parameters. Finally, it is compared with
the common PID controlling method. In this system, the result of simulation shows less control effort and
more appropriate performance for MRAC.
