Lab 3: 2-DOF State-Feedback Control

Block Diagram of Balance State-Feedback Control for Rotary Pendulum
In this lab, students will learn about the limitations of PID or PD control, and the benefits of an optimal controller such as the Linear Quadratic Regulator (LQR). Students will explore the Linear Quadratic Regulator State-Feedback Control with regards to the 2-DOF helicopter Aero configuration in this lab.
