....control systems, robustness of stability is an essential problem that requires particular consideration. Indeed, due to the finite word length e#ect, a nominal stable system may have unstable behaviours. Extensive research work has been conducted on designing robustly stable systems. See, e.g. [1, 16, 10, 12, 6]. One approach is to design the system not only to be merely stable but also possess a su#ciently large stability margin, which can prevent the occurrence of some kind of unfavarable behaviour of the system. For example, the robustness of the stability of a 2 D system against parameter variation ....

....3 Stability Margin and Stabilizability Margin In practice, due to the uncertainties in the system parameters and the finite word length e#ect, a nominal stable system may have unstable behaviours. Extensive research work have been conducted on designing robustly stable systems. See, e.g. [1, 6, 10, 12, 16]. One approach is to design the system not only to be merely stable but also possess a su#ciently large stability margin, which can prevent the occurrence of some kind of unfavarable behaviour of the system. A large stability margin also makes the impulse response of a system fast to reach the ....
