摘要
The operation environment, working conditions and some other reasons make some motor parameters unable or difficult to be measured by conventional measurement instruments directly a soft measuring method based on recursive least squares method to identify motor parameters on-line is presented. The on-line identification is realized by the establishment of the steady-state mathematical model of the induction motor and the use of recursive least squares method. The system simulation model is built in the MATLAB/SIMULINK environment, and experimental results verify that this method is useful to identify the motor parameters accurately and rapidly.
