Abstract

In this paper, it is pointed out that we can realize the high-precision fuzzy control by the use of the quotient space theory (a method of granular computing). With the changing of control granularity, we can roughly adjust the parameters of control system on the level of coarser granularity; conversely we adopt the strategy of delicate adjustment to tackle with finer granularity, the system can achieve good stable and dynamic performances. The above-mentioned turns out to be right in the practices.
