Recently, Fuzzy reasoning has been used in many fields of applications. In the application of the fuzzy reasoning to various fields, the tuning and optimizing method is the key issue. Some self-tuning methods have been proposed so far. Most of these conventional self-tuning methods require teaching data or a mathematical model of the environment in order to tune the fuzzy systems. However teaching data are not obtained in many cases, because of the nonlinear property of the control objects. In this paper, we propose a new unsupervised self-tuning method for fuzzy resoning. The fuzzy reasoning consists of some membership functions expressed by the radial basis function with an insensitive region. The unsupervised learning is carried out by the genetic algorithm, which has two mutation operators for global and local searches. The effectiveness of the proposed method is shown through simulations of the force control for uncertain objects.
