Abstract :
For the purpose of field oriented control, a Kalman filter structure is used to obtain the unmeasurable rotor flux of an induction motor, thereby eliminating virtually all influence of discretisation and structural noise. The speed and position control has been implemented on a floating point 32 bits, RISC architecture 80960SB INTEL microprocessor. The calculation of the space vector modulation laws is performed proceeding directly from the instantaneous input voltage by using a 80C196KC INTEL microcontroller. Design criteria and control implementation are described. Experimental results are given with a pulse switching frequency of 600 Hz, intended to high power induction motor drives
