Evaluation of microcontroller architectures for PMSM control

Due to hybridization of vehicles, electrical motors like permanent magnet synchronous motors (PMSM) are playing a major role in the automotive industry. In order to upgrade the micro-controller used for the prototype of the PMSM control in Volvo Group Truck Technology, a study on available micro-controllers presently on the market and to evaluate a few of the suitable micro-controllers is necessary. In this thesis a evaluation of Texas instrument micro-controllers TMS320F28377D and TMS570LS1227 are performed. In the first part of the thesis, a digital con-trol algorithm has been implemented in the Matlab simulink and effect of various digital control parameters like ADC resolution, PWM resolution, ratio of switching frequency to electrical fre-quency of stator current etc. has been discussed. Based on the simulation minimum requirements of PWM and ADC resolution has been found to be 10 bit. Also the simulation results showed that for the drive system under consideration the ratio fsw/felec should be 40 or more to have a better torque control. In the second part of the thesis the best available micro-controllers suitable for PMSM con-trol has been listed and the two of the most suitable micro-controllers TMS320F28377D an
