Lab 2: 2-DOF PD Control

Proportional-Velocity (PV) Control Block Diagram
In this lab, students will be exposed to some basic specifications for a 2-DOF helicopter, and learn how to design a controller to meet those specifications. In most systems, there are two types of control methodologies - open loop control and closed loop control. In the former, the control effort is proportional to the output variable. To automate this system, feedback from the system can be used to modulate the control effort and bring the output variable to a setpoint or the desired value.
