摘要：
The aim of this paper is to present a simplified vector control implementation without current sensors in order to reduce cost of overall system, design complexity, and improving by using proportional-integral fuzzy logic control (PI-FLC) for high performance in wide-speed-range operation. In this scheme, voltage source inverter used space vector pulse width modulation (SVPWM) technique that is good voltage utilization and low total harmonic distortion (THD), where voltage control signal of inverter is derived from indirect vector control (IVC) theory and dynamic motor equation. The complete PI-FLC vector control was experimentally implemented using dsPIC4011 board for 1/2-hp squirrel cage induction motor (IM). This proposed control system was compared with conventional proportional-integral (PI) control validated by MATLAB/Simulink and experiment. Both control techniques were tested at different dynamic conditions such as sudden speed change and speed tracking. The comparative experimental results show that the PI-FLC vector control is more robust for this application.
