Abstract
It is shown in this note that the fuzzy controller with (locally) line ar control rules used in Ying (1994) cannot be linearized around the o rigin, and therefore local stability of closed-loop systems including this type of fuzzy controller cannot be analyzed by means of the Lyapu nov's first method. Besides, it is proved that, with another choice of inference law, the fuzzy controller with (locally) linear control rul es can be linearized in a neighbourhood of the origin.
