As the extension of traditional linear (or X) inverted pendulum (IP), X-Z IP is a multiple-input multiple-output (MIMO), underactuated, open-loop unstable, and nonlinear system. In tracking control IP, equilibrium point changes with pivot position pendulum. This makes theories have difficulties in realization for The underactuated feature feedback linearization unsuitable to simplify design. Wi...
