Name of the equipment: 2 DOF HELICOPTER Make & Model: TecQuipment CE-150 I-Stem Registration ID- ……………………..                               Category of Instrument Laboratory work bench instruments Types of Analysis / Testing Validation of control strategy Application: · Derivation of simple dynamic model · State space representation · State feedback control with feed forward and integral anti-windup · LQR control design · Control parameters tuning · It can be used to understand and develop control laws for a vehicle that has dynamics representative of a dual rotor rigid body helicopter, or any device with similar dynamics Description of Instrument The 2 DOF Helicopter emulates a helicopter configuration with a main rotor and anti-torque tail rotor. The front propeller controls the pitch axis – rotating the center of the body about the horizontal. The back propeller controls the yaw axis – the angle about the vertical base. Both axes are measured using high-resolution encoders. The slip ring mechanism on the vertical axis allows the body to freely rotate about the yaw angle, by eliminating the need for any wires to connect the motors and encoders to the base.
