Optimal realization of FWL controller with real stability radius considerations
有限字长数字控制器的实稳定半径最优实现

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.
