Abstract

When we take into account more input variables in a control system, the number of rules grows exponentially. To decrease the number of rules, we propose not to explicitly state the control for every combination of input variables, but to use the "otherwise" clause. In this paper, we provide a simple statistical analysis of the resulting reduction and show, on a case study, that this reduction can indeed be drastic.
