This paper explains the talented impact of utilizing the Adaptive Neuro Fuzzy Inference System (ANFIS) technique on enhancing the performance of the generator Loss-of-Excitation (LOE) protection. In this context, investigations are conducted on a two-hydro generator power station model under a complete Loss of Excitation (LOE) conditions and a partial Loss(More)
The main objective of Load Frequency Control (LFC) is to regulate the power output of the electric generator within an area in response to changes in system frequency and tie-line loading. Thus the LFC helps in maintaining the scheduled system frequency and tie-line power interchange with the other areas within the prescribed limits. Most LFCs are primarily(More)
In this paper, a new artificial intelligence technique, Harmony Search (HS), will be used for the optimization of a classical order PID for a two-area load frequency control (LFC) model using the participation factor concept. The HS has four main variants, these variants had been used for the optimization of classical order PID controllers in case of(More)
This paper presents a new approach for Loss of Excitation (LOE) faults detection in Hydrogenerators using Adaptive Neuro Fuzzy Inference System. The proposed scheme was trained by data from simulation of a 345kV system under various faults conditions and tested for different loading conditions.

Robotic manipulator is a Multi-Input Multi-Output (MIMO), highly nonlinear and coupled system. Therefore, designing an efficient controller for this system is a challenging task for the control engineers. In this paper, the Fractional Order-FuzzyProportional Integral Derivative (FO-Fuzzy-PID) controller is investigated for the first three joints of robot(More)
This Paper presents a model of Wind Energy Conversion System (WECS) using Permanent Magnet Synchronous Generator (PMSG). This system is a grid connected system and contains two power converters and capacitor bank. This system is controlled by PI control for controlling the Voltage Source Inverter (VSI). Particle Swarm Optimization (PSO) code is used to(More)
Power systems are highly nonlinear systems that exhibit undesirable oscillations following disturbances. Power system stabilizers (PSS) are usually incorporated to provide auxiliary excitation signals to damp these oscillations. Our objective is to improve the PSS performance via the use of fuzzy logic and LMI techniques. A power system is viewed as a(More)
