Inverted Pendulum System
Inverted Pendulum System is a physical device consisting in a cylindrical bar which is usually made of aluminium, free to oscillate around a fixed pivot. The pivot is mounted on a cart, which can only moves in a horizontal direction. The cart can be exerted by a variable force. The bar would natu...

| Summary: | Inverted Pendulum System is a physical device consisting in a cylindrical bar
which is usually made of aluminium, free to oscillate around a fixed pivot. The pivot is
mounted on a cart, which can only moves in a horizontal direction. The cart can be
exerted by a variable force. The bar would naturally tend to fall down from the top
vertical position, which is a position of unsteady equilibrium. The goal of this project is
to stabilize the inverted pendulum from falling down. This is possible by exerting on the
cart through the motor a force which tends to contrast the 'free' pendulum dynamics.
The correct force has to be calculated measuring the instant values of the horizontal
position and the pendulum's angle. There is two controllers used and compared which
are the PID controller and LQR controller. The modelling and analysis is done for both
of these controllers in MA TLAB and Simulink. After that, the performances of these
controllers are analyzed especially on the time taken to stabilize the pendulum and also
the cart position. Therefore, the best control approach needs to be discovered in order to
give the best performance for the inverted pendulum system. |
