Estimation of Speed and Torque of Three-phase Induction Motor Based on Central Difference Extended Kalman Filter Algorithm
摘要
Abstract
In the process of there-phase induction motor speed and torque estimation,the data collec-tion is vulnerable to the outside interference easily,which leads to large deviations.Speed and torque es-timation method of there-phase induction motor based on central difference extended Kalman filter was proposed.At first,deduced there-phase induction motor state equations and output equations in theα-βcoordinate system with three-phase induction motor stator and rotor currents as state variables.Then u-sing central difference extended kalman filter algorithm for three-phase induction motor speed and torque estimation.The simulation results show that,compares with extended kalman filter,central difference extended kalman filter algorithm has better follow-up performance when motor running state changes, and has faster rate of convergence.Thus speed and torque of there-phase induction motor can be esti-mated precisely.关键词
