It's difficult to make a comparison between the PID and LQR control methods , both can be adjusted by hand after the initial guess and can show satisfactory results.However , the main advantage of using LQR on this case is that the energy input can be controlled (at the [R] matrix ). Both methods requires a hand tuning after the initial guess to achieve the desired response. | It's difficult to make a comparison between the PID and LQR control methods on this ball and beam case , both can be adjusted by hand after the initial guess and can show satisfactory results.However , the main advantage of using LQR on this case is that the energy input can be controlled (at the [R] matrix ).

| Usually you will want to use Full State feedback using LQR insted of PID - PID can be limited in some situations. On the Rotary Inverted Pendulum for example , using only PID Control is not enough to get a good pendulum balance. |
