%X An optimal realization algorithm is discussed for a finite-word-length (FWL) digital controller in a typical sampled_data feedback system. The FWL controller optimization is realized through a real closed-loop stability radius measure. The optimization produced an optimal state transformation matrix as well as the optimal structure and minimum word_length of the controller, The numerical example proves that a larger stability radius can be obtained using an optimal controller with smaller word length.
