Self-commissioning for voltage-referenced voltage-fed vector controlled induction motor drives

This paper describes an automated self commissioning procedure for voltage referenced voltage fed vector controlled induction motor drives. A method for off-line determination of machine electrical parameters is presented. The measurement of the motor electrical variables at standstill time-domain test is used as an identification procedure base. Experimental results achieved with a 10 HP induction motor drive show good agreement between estimated and nominal electrical parameters. The proposed strategy is compared with other identification mechanisms, previously described in the literature, that have been improved with a proposed off-line current-dependent σL_s adaptation mechanism to obtain better accuracy. Results show similar behaviour using both identification schemes although the proposed scheme requires simpler tests
