Analysis of Single-Phase Induction Motors Efficiency Optimization Control with Hall Sensor

This thesis deals with the optimization control of a single-phase induction motors with Hall sensor. A simple modeling method with feasible parameter identification is adopted to meet characteristics of single-phase induction motors. With the linear Hall sensor feedback, the advantages of current-mode control scheme and soft-commutation scheme are proposed to achieve maximum efficiency over the entire speed range. This thesis also develops a low-cost and high efficiency control for single-phase induction motors. The hardware test platform has been constructed on a single-chip Field Programmable Gate Array of Cyclone II Family of Altera to verify the performance and feasibility of the proposed optimization control strategies. The control scheme has been verified by computer simulation based on the proposed model. Some experimental results have been shown to verify the performance and feasibility.
