In this paper, a complete system of quad rotor stability mechanism was designed and implemented. Starting with a Single-axis Implementation of a Quad rotor, SISO approach is implemented for control structure to achieve desired objectives. The tradition PID, modified PID controllers and Adaptive Neural fuzzy inference system (ANFIS) were executed on simulation model of Quadrotor. The performance of the designed control structure is evaluated through processor in loop experiment and through the time domain factors such as overshoot, settling time. The evaluation results reveal that the designed modified PID controller has the best performance, more robust, higher stability and less control effort compared to the original and designed ANFIS controller. Three axis test and implementation of the algorithm has been performed and the results are discussed.
