The complete drive control system is discrete, is developed in Simulink model which is converted in C via
Code Composer Studio (CCS), in order to be implemented using the platform eZdsp from Digital Spectrum based on
the fixed point 32 bit DSP TMS320F2812 from TI. Due to limitations in the memory size (when Matlab is linked with
CCS in the simulator mode), only 32 Kbyte data can be processed. The inverter DMC1500 is interfaced with the
eZdsp. The fuzzy system is activated every 0.5 s. The tested motor is a 1Hp, 3x380 V, rated speed 1390 rpm. The motor
drive is tested by simulations and experiments in order: (i) to validate the efficiency improvement of the proposed control
method and (ii) to compare the response with a sudden load step for different methods (the proposed method with and
without transient optimum flux recovery).
