This investigation improves the performance of a direct torque controlled permanent magnet synchronous motor (PMSM) using both genetic algorithm (GA) and fuzzy logic. In this approach electromagnetic torque error, stator flux linkage error and stator flux angle are fuzzified using three appropriate fuzzy sets. Therefore the best voltage space vector has(More)
Abstract– In this paper, vibration suppression and control of a smart flexible satellite maneuvering in a circular orbit are studied. The satellite is considered as a rigid hub and two flexible appendages with PZT (lead zirconate titanate) layers attached on them as sensors and actuators. Flexible satellite governing equations of motion are obtained using(More)
Background: The modern life style despite its comforts has made cancer a leading public health problem. As chemotherapeutics has many side effects including resistance, recent attention has focused on plants which may provide a good opportunity for complementary cancer treatment. Aloe vera has been described as a wonder plant due to its many advantages. It(More)
In this investigation a vector controlled permanent magnet synchronous motor (PMSM) is simulated and then a wavenet (a neural network based on wavelet functions) based speed controller is designed to make the system more robust against parameter variations. The data for training the network is extracted from a process with several PID controllers to achieve(More)
