A Operating by the Direct Thrust Control of SLIM in Conveyor System |
| Abstract |
In this paper, the thrust control of PWM Inverter-Fed SLIM(Single-sided Linear Induction Motor) is achieved with Space Vector control and PI control. The trembling of air gap length which is occured between the primary winding core and the secondary structure of the SLIM must be minimized in order to get quick response characteristics. First, the equivalent circuits and voltage equations of SLIM axe shown on the suitable d-q axis which analyze characteristics of the thrust and the normal force. Also, modeling and analysis of the equevalent circuits transfered d-q axis are able to make robust transient torque from the current regulation in the equivalent circuit. These results exemplified the direct chive of SLIM with the reference speed and torque were verified by expel flints. |
