Modelování a simulace střídavého pohonu s přirozeným řízením v programu Matlab-Simulink

Abstract

This diploma thesis is verify the simulation control of induction motor without speed sensor. This metod of control is called NFO (Natural Field Orientation). NFO allows us estimate mechanical angular velocity, if we exactly know the parameters of the induction motor. In Matlab-Simulink were created for comparison classic vector control with speed sensor and two variants NFO control (without speed sensor). There were created simplified and advanced NFO.Simulation results will demonstrate the proper functioning of the method. This NFO method is able control induction motor without speed sensor.
