This paper considers the stability problems of continuous- and discrete-typ
e fuzzy control systems, respectively. On the basis of matrix measures and
matrix norms, several stability criteria for the systems are proposed. Some
of these criteria are flexible with different chosen parameter "p". That m
eans, the trade-off between the conservativeness and the computing convenie
nce of the criteria depends on the chosen value of "p" totally. (C) 1999 El
