Design and implementation classical, state feedback and fuzzy controllers on twin rotor system

In this paper, design, manufacturing and control of a twin rotor system is studied. The pitch angle of the system is controlled by several methods. We could access to desired pitch angle of the system via two angle and angular velocity sensors precisely. Three controllers, PID, state feedback, and fuzzy controllers are designed and implemented to the system. In this system, fast rise time and a little overshoot are our desired response specifications. It has been shown the PID has an unacceptable overshoot and the fuzzy controller rise time is very large although it does not have overshoot. Transient response of the state feedback controller is within the fuzzy controller and the PID one. There are not so different from each other from sinusoidal responses point of view although the fuzzy controller has a slower response than others.
