Abstract
Single phase induction motors run at constant speed and hence finds its application not only in the industries but also in the traditional home appliances and low power rural equipments. The traditional method followed for speed measurement use sensors that are cost effective. A sensor less system is suggested where the speed is estimated instead of measured would considerably reduce the cost and complexity of the drive system. In the proposed system a sensor less indirect stator flux oriented control using fuzzy logic is implemented to control the single phase induction motor drive. Among various control methods the field oriented control (FOC) is widely used to obtain a high dynamic performance and provide a better solution to satisfy emerging industrial requirements. The main and auxiliary winding stator currents are measured and a reference q-axis current is generated through the control algorithm which is fed in the embedded system. The error of the measured q-axis current from its reference value feeds the integral controller. During recent years, many research laboratories have focused on variable-speed drives, especially for the SPIM, and major improvements have been achieved. The availability of low-cost static converters makes possible the economic use of energy and improvement of the quality of the electromagnetic torque in SPIM
