An Application of Fuzzy PID Algorithm on Unmanned Helicopter Attitude Control

the design of an attitude controller for an unmanned helicopter is addressed. The controller proposed is based on fuzzy PID algorithm, and is used for stable and robust roll, pitch, and yaw control. The fuzzy logic rules are established through a combination of expert knowledge and experiment data which is obtained from a real unmanned helicopter platform. Both the simulation and the experimental results verify the validity of fuzzy PID algorithm which integrates the advantage of fuzzy control and PID control
