Abstract:
This paper obtains feedback stabilization of an
inverted pendulum on a rotor arm by the "method of controlled
Lagrangians". This approach involves
modifying the Lagrangian for the uncontrolled
system so that the Euler-Lagrange equations derived from the
modified or "controlled" Lagrangian describe the closed-loop
system. For the closed-loop equations to be consistent with
available control inputs, the modifications to the Lagrangian
must satisfy "matching" conditions. The pendulum on a rotor arm
requires an interesting generalization of our earlier approach
which was used for systems such as a pendulum on a cart.
