Dynamic Flux and Torque Estimation of Single-Phase Induction Motors Based on the Vector Control Theory of Motors

摘要

A method for flux and torque estimation for the single-phase induction motors is presented in this paper. This work is based on the vector control theory of electrical machines, and has realized an estimation of flux and torque and some intermediate variables like direct and quadrature values. Accordance with the algorithm, a basic experimental model is built in the Simulink of the Matlab and tested for sinusoidal waveforms feeding the single-phase motor. Simulation experiments show that the methods are correct and the estimation is effective to access to internal parameter of the single-phase induction motors in order to obtain AC drives with high performance.
