Control and Stabilization of Pitch Axis Angle In 3 DOF Titltrotor

Tiltrotor system is used in army for security purpose and mission attack. This system is affect due to environment conditions such as wind flow, rain and low atmospheric pressure, the system becomes unbalanced in working conditions. In recent days new control technique called fractional order PID have a conspicuous growth in the field of controller design for controlling the various linear and nonlinear system applications. The fractional order PID controller used in tiltrotor model, improves the system performance compared with other controllers. The proposed work deals with the Pitch axis control of tiltrotor system using FOPID controller and also performance has been compared with PID controller, with different tuning methods. The FOPID controller provide more flexibility in designing a controller than using PID controller due to selection of tuning parameters. FOPID and PID controller has been designed for pitch axis control, the performance characteristics of the system has been compared and analyzed by using MATLAB simulation.
