Simulink Generated Control Algorithm for Nine-phase PMS Motor
MetadataShow full item record
This paper deals with the nine-phase motor control algorithm development, mainly with its implementation in target hardware using MATLAB Simulink. This environment allows control algorithm design using model based approach and the subsequent automatic conversion of control algorithms into C code using Simulink Embedded coder which is then used in the inverter software. Field oriented control algorithm has been designed and tuned for this motor. Control algorithm has been tuned according to the measured motor parameters in simulations and then fine tuned on a real motor. The inverter control unit is based on AURIX Tricore microcontroller TC275. The code generation in Simulink has many settings. This paper analyses computational time depending on these settings. Potential problems with floating point math functions are outlined. Automatic code generation proves to be quick and easy tool for replacement of control algorithms or for fast control algorithm adaptation to different hardware.
