Visually impaired has limited movement using the classic white cane. Currently, there are many designs for devices that can assist the blind moves better in unfamiliar environment. Then, controllers were applied in the devices’ system so that it can improve the system’s efficiency and accuracy in dealing with real-time situations. That’s when the intelligent system was introduced in the field t...

The theory of fuzzy sets with reference to subnormality needs to be properly explained. We shall in this article put forward the actual mathematical explanation of subnormal partial presence of an element in a set, better known as subnormal fuzziness. We shall first show that every law of subnormal fuzziness can be expressed in terms of two Lebesgue-Stieltjes measures. Thereafter we would defin...

Fuzzy control has been widely used in industrial controls, particularly in situations where conventional control design techniques have been difficult to apply. Number of fuzzy rules is very important for real time fuzzy control applications. This paper proposes a novel approach called block based fuzzy controllers. This study is motivated by the increasing need in the industry to design highly...

It is given a new algorithm to compute a lower T-transitive approximation of a fuzzy relation that preserves symmetry. Given a reflexive and symmetric fuzzy relation, the new algorithm computes a T-indistinguishability that is contained in the fuzzy relation. It has been developed a C++ program that generates random symmetric fuzzy relations or random symmetric and reflexive fuzzy relations and...

This work presents an efficient method based on a modified fuzzy PI control with parallel fuzzy PD control for automatic generation control (AGC) of a two-area power system. This describes the control schemes required to operate the two-area power system in the steady state. The model of a two-area power system is established using the equations describing dynamic behaviour of a two-area power ...
