In the body of the dissertation , different performance indexes are defined and analyzed based on the analysis of different types of fwl errors in digital controller , and different fwl digital controller design and realization problems are considered and solved . the major contributions of this dissertation are as follows : considering the fwl errors of controller coefficients , define and analyze the closed - loop transfer function sensitivity measure with respect to the controller coefficients , obtain the optimal controller realizations via minimizing the transfer function sensitivity measure 本論文首先對數(shù)字系統(tǒng),特別是數(shù)字控制器設(shè)計(jì)與實(shí)現(xiàn)中的有限字長問題和非脆弱控制器設(shè)計(jì)的背景、歷史發(fā)展情況等作了簡單介紹,然后通過分析數(shù)字控制器中不同來源的有限字長誤差,定義不同的性能指標(biāo),較系統(tǒng)地分析并討論不同的有限字長數(shù)字控制器設(shè)計(jì)和實(shí)現(xiàn)問題。
