Adaptive fuzzy controllers based on variable universe. (English) Zbl 0935.93042
The interpolation mechanism for fuzzy control, previously introduced by the same author [ibid. 41, No. 3, 312-320 (1998; Zbl 0916.93041)], is exploited in the construction of adaptive control architectures. The approach relies on the concept of monotonicity of control rules, which is proved equivalent to the monotonicity of interpolation functions of fuzzy control. The structure of contraction-expansion factors of variable universe is used to develop and study three types of adaptive fuzzy controllers called “with potential heredity”, “with obvious heredity” and “with successively obvious heredity”, respectively.
