Inverted Pendulum NI ELVIS Controls Device—The Quanser QNET Rotary Inverted Pendulum Board 2.0 for NI ELVIS II/II+ is an add-on application board for the NI Engineering Laboratory Virtual Instrumentation Suite II (NI ELVIS II) or NI ELVIS II+. This device has been developed for education to facilitate hands-on, active learning of the fundamentals of nonlinear control, stability, damping, state feedback, linear–quadratic regulator (LQR), and hybrid control through a pendulum. By designing a control system that balances a vertical rod on a rotating arm, students develop engineering intuition on a broad range of controls topics.
