| Abstract: | This paper presents a novel approach to the stator flux control of the induction motor,in which the latest and low cost single-chip-microcomputer type 80C196KC is used as theCPU of the controller,A new switching control rule database is developed using SPWMswitching rules. Real time closed-loop direct control for the stator flux vector loci is realizedand the control system is fully digitalized.Compared with conventional direct torque controlmethods,the approach proposed has considerably improved the combined control of the fluxand torque and the effectiveness of the algorithm. Digital simulation and results of experi-ments on a 1.1 kW induction motor have proved the effectiveness of the strategy. |
