For simplicity, I assumed whole balancing system as an inverted pendulum. In this script, an angle of 0 is chosen to be at the top (yes, it is more convenient to choose 0 at the bottom, but this works too) The reason why choosing an initial angle of 0 yields a constant-0 angle plot is that it can stand exactly upright without movement, try choosing 0.00001 and you'll see it fall down to pi eventually. - GitHub - Arcane-01/Cart-Pole: Designing a PID and a LQR controller to balance an inverted pendulum. In this script, an angle of 0 is chosen to be at the top (yes, it is more convenient to choose 0 at the bottom, but this works too) The reason why choosing an initial angle of 0 yields a constant-0 angle plot is that it can stand exactly upright without movement, try choosing 0.00001 and you'll see it fall down to pi eventually.
