Abstract

The industrial requirements for the control of an induction machine without a mechanical sensor continue to be of interest, as evidenced by the most recent publications. The focus is on improvements of control without a mechanical sensor. A new method for the implementation of a sensorless indirect stator-fluxoriented control (ISFOC) of a single-phase induction motor (SPIM) drive is proposed in this paper. The proposed method of rotor speed estimation is based only on the measurement of the main and auxiliary windings stator currents and that of a reference q-axis current generated by the control algorithm. The error of the measured qaxis current from its reference value feeds the proportional plus integral controller, the output of which is the estimated slip angular frequency. Experimental results for sensorless ISFOC speed control of a SPIM drive are presented and analyzed using a dSPACE system with DS1104 controller board based on the digital signal processor TMS320F240. Digital simulation and experimental results are presented to show the improvement in performance of the proposed sensorless algorithm. Index Terms—Indirect stator-flux-oriented control, sensorless vector control, single-phase induction motor, speed estimation.

 INTRODUCTION

SINGLE-PHASE induction motors (SPIM) are traditionally used in constant speed home appliances, usually in locations where only single-phase energy supply is available without any type of control strategy. They are found in air conditioners, washers, dryers, industrial machinery, fans, blowers, vacuum cleaners, and many other applications. Variable speed controls of electrical motors are widely employed in industrial applications because of the obvious energy-saving benefits. The cost reduction and high efficiency of power electronic and microelectronics devices are motivating to implement a SPIM drives in both industrial and domestic applications. During recent years, many research laboratories have focussed on variable-speed drives, especially for the SPIM, and major improvements have been achieved.
