Tandem Rotor Helicopter Control

2018
In this chapter, we study the dynamic analysis and control design for the tandem rotor 3-DOF helicopter platform. We utilized the MATLAB/Simulink software to integrate with the Quarc software for the control system. The system mimics a Chinook helicopter, of which the build consists of a base to which an arm is mounted, two motor-driven propellers ...
