In this paper, an internal model control recurrent neural network method is used to control the switching of thyristor-controlled reactor in a static VAR compensator (SVC) system for regulating the voltage. The novel controller scheme contains several feedback loops instead of only a feed-forward loop as in the conventional recurrent neural network (RNN). In the proposed controller model, the RNN...
In this paper, we presented an optimized fuzzy logic controller using particle swarm optimization for DC motor speed control. The controller model is simulated using MATLAB software and also experimentally tested on a laboratory DC motor. A comparison of the performance of different controllers such as PID controller, fuzzy logic controller and optimized fuzzy logic controller is presented as well...
In this study, simply two systems consist of series of microring resonators (MRRs) and a add/drop filter are used to generate a large bandwidth signal as localized multi wavelength, applicable for quantum dense coding (QDC) and continuous variable encoding generation using incorporated system. This technique uses the Kerr nonlinear type of light in the MRR to generate multi wavelength for desired...
We investigate nonlinear behaviors of light known as bifurcation and chaos within a nonlinear silicon microring resonator (SMRR). The research is used to controlling SMRR's behaviors such as chaos applicable in security coding systems. The variable parameters affect the bifurcation to be happened in smaller roundtrip among total round trip of 20000 or input power. Simulated Results show that rising...
This paper presents Generator Aggregation which is an important technique in power system analysis. This method relies on faults and variation of voltage in power transmission system. Voltage and frequency will vary when fault occurs in the power system. Fault study can be simplified by using generator aggregation. Inertia aggregation techniques which are based on processing assessment of the fault...
In this paper, a photovoltaic array has been modeled and developed for MATLAB-Simulink environment. The PVA model has been developed by basic circuitry equations of a photovoltaic array, considering the effects of ambient temperature, solar radiation and natural specifications of the photovoltaic cell. For evaluating the model, two different types of the loads have been utilized, a direct coupled...
