Two approaches have been proposed for adjusting the parameters of a PID controller. Foremost, the PID controller gains are settled in an ideal way by using a reference model strategy. In the moment approach, these parameters are adjusted Nonlinear PID. MATLAB/Simulink has been utilized to test and compare the execution of the controllers gotten. The obtained results using the nonlinear PID controllers show the efficiency of the proposed controllers it presents a response with less error and minimal over shoot compared to the results of classical PID controller.enPID Controller; Reference Model; Nonlinear system; Quadcopter.Article
