Improved Sensorless Direct Torque and Flux Control of Three Phase Synchronous Reluctance Motor Drive Based on Adaptive Nonlinear Control Hossein Abootorabi Zarchi abootorabi9@yahoo com June 2010 Department of Electrical and Computer Engineering Isfahan University of Technology Isfahan 84156 83111 Iran Jafar Soltani Supervisor j1234sm@cc iut ac ir Gholamreza Arab Markadeh Advisor S Mahmood Moddareshashemi Department Program Coordinator Department of Electrical and Computer Engineering Isfahan University of technology Department of Engineering University of Shahrekord Abstract In this thesis direct torque and flux control of three phase synchronous reluctance motor SynRM drives is improved based on adaptive nonlinear control The SynRM drive is supplied with a two level symmetrical space vector modulation SVM voltage source inverter Two estimation laws are obtained by adaptive input output feedback linearization AIOFL for detecting the stator d and q axis inductances The overall stability of this controller is analytically proved based on Lyapunov theory In addition a flexible direct torque control DTC based on Variable Structure VS and SVM is presented for sensorless SynRM Drives According to this method a sliding mode plus PI controller is designed for torque and flux control in stator flux reference frame respectively The proposed controller is able to reduce the torque flux current and speed pulsations during steady state behavior while the fast response and robustness merits of the classic DTC are preserved In addition an on line adaptive loss minimization controller ALMC for SynRM drives is introduced The ALMC provides a novel pattern of change in stator flux magnitude to achieve a minimum motor input power at any operating condition The operating of the ALMC results in a smooth and fast loss minimization Very low speed estimation 5 rpm is satisfied by the elimination of the voltage sensors dc offset The proposed control techniques are experimentally implemented using a CPLD board synchronized with a personal computer Simulation and experimental results are presented to verify the effectiveness of the proposed methods Key Words Synchronous Reluctance Motor Direct Torque Control Adaptive Input output Feedback Linearization Variable Structure Efficiency Optimization
