Notes:
The condition number of the process transfer function G(s) has been proposed and used as an indicator of the inherent controllability of a process even though it is a scale-dependent quantity. A rapid suboptimal scaling policy known as G-balancing is developed for the case of the l2 norm where the condition number is the ratio of the largest to the smallest singular value of G(s). For 2 × 2 systems, G-balancing gives the same optimal scaling as an available analytical solution. The higher order examples given compare the results of G-balancing with the known analytic results for l2 norm optimal scaling.
