A Computational Investigation of Pole-Zero Cancellation for a Double Inverted Pendulum System.

Woodham, C A; Su, H

Abstract

Modern symbolic computational systems which perform automated manipulation
of algebraic variables offer insights into a variety of mathematical
problems. This work uses the symbolic manipulation toolbox available in
MATLAB to investigate pole-zero cancellation of the uncontrollable double
inverted pendulum algebraically, following exploratory numerical
computation. The ability of the software to factorise complicated
multi-variable polynomials is exploited to identify, in algebraic form, the
anticipated pole-zero term cancelling throughout the transfer functions of
the uncontrollable pendulum system. This problem has been considered with respect to the force on the trolley, for which it is a conditionally
uncontrollable problem, and with respect to each of the torques on the arms,
which are unconditionally uncontrollable problems. Pole-zero cancellation
for the triple inverted pendulum system is currently under consideration.
