Many spectrum methods have been proposed to use spectrum effectively, the opportunistic spectrum access has become the most viable approach to achieve near-optimal spectrum utilization by allowing secondary users to sense and access available spectrum opportunistically. However, a naive spectrum access for secondary users can make spectrum utilization(More)
In this paper, a self tuning Proportional Integral Derivative (PID) with PSS controller is presented for improving stability of a system in simulink environment. The development of a PID with power system stabilizer in order to maintain stability and enhance the performance of a power system is described widely. The application of the PID with PSS(More)
The main objective of this research work was to develop a Cluster Analysis based fault identification model for the power system. Cluster Analysis based Data Mining Techniques model has been implemented to locate the 3-phase transmission lines fault in IEEE 30 bus power system. Power World version 18 software was used to simulate the IEEE 30 bus power(More)
It is known that PID controller is employed in every facet of industrial automation. The application of PID controller span from small industry to high technology industry. In this paper, it is proposed that the controller be tuned using Adaptive fuzzy controller. Adaptive fuzzy controller is a stochastic global search method that emulates the process of(More)
