The paper describes a new proposed algorithm to automatically tune a Fuzzy Logic Controller by using motor Speed profile and Genetic Algorithm (FLCSGA algorithm) in controlling a DC Servo Motor. In the new method, the tuning process of the Fuzzy Logic Controller (FLC) is divided into two consecutive stages which are tuning rule base and tuning Membership Functions (MFs). The tuning rule base (F...

A novel reconfigurable membership function circuit (RMFC) for analog fuzzy logic controller (FLC) is presented. The reconfigurable characteristic makes it more suitable in industrial control applications when compared with the MFC proposed in [1]. By proper signal arrangement, the RMFC can re-sample the same input current in different configuration, which reduces the number of MFC in analog FLC...

In this paper, structure of fuzzy logic controller is presented. Power systems are subjected to low frequency disturbances that might cause loss of synchronism and an eventual breakdown of entire system. These oscillations limit the power transmission capability of a network and cause loss of synchronism. Power system stabilizers (PSS) are used to damp these low frequency oscillations by provid...
