![]() The results shows that the Neuro-controllers and Neuro - Fuzzy controllers have excellent responses for all SG models and loads in view point of transient response and system stability. The concerned neural networks and Neuro - Fuzzy controllers for AVR is examined on different models of SG and loads. The fuzzy models under the framework of adaptive networks are called Adaptive-Network-based Fuzzy Inference System (ANFIS), which possess certain advantages over neural networks. ![]() The essential part of Neuro-Fuzzy comes from a common framework called adaptive networks, which unifies both neural networks and fuzzy models. The Nonlinear Auto-Regressive Moving Average (NARMA-L2) model system is proposed as an effective neural networks controller model to achieve the desired robust Automatic Voltage Regulator (AVR) for Synchronous Generator (SG) to maintain constant terminal voltage. Modern power systems are complex and non-linear and their operating conditions can vary over a wide range. Also intelligentĬontrollers improved robustness of AVR over the PID controllerĪbstract- Artificial Neural Networks (ANN) and Neuro - Fuzzy controllers can be used as intelligent controllers to control non-linear dynamic systems through learning, which can easily accommodate the non-linearity’s, time dependencies, model uncertainty and external disturbances. Less settling time than PID controller with different conditions of load. Intelligent controllers shows less over shoot, less rise time and Due to this fact, it becomes necessary to look for another controller with better Nonlinearities due to theĮffect of saturation in machine between generated voltage and field current, uncertainties ariseīecause variation of the load connected with time and the change of rotors resistance with ![]() (NARMA-L2) and Neuro-fuzzy controller as intelligent controllers. This paper proposes a Nonlinear Auto Regressive-Moving Average control Nonlinearities and parametric uncertainties are unavoidable problemįaced in controlling the output voltage of Synchronous Generator (SG) when working alone or Nowadays, design technology of AVR isīeing broadly improved. Operation of Aِِutomatic Voltage Regulator (AVR). The voltage stability and power quality of the electrical system depend on proper
