PARTICULARITIES OF ROTOR FIELD ORIENTATION CONTROL IMPLEMENTATION ON INDUSTRIAL DSP SYSTEMS

The aim of this paper is the experimental implementation and validation of field-oriented control for asynchronous machine traction systems, on the one hand, with a special interest in the motor flux estimator and the implementation intricacies specific to the DSP implementation of discrete control systems, on the other hand. The implementation was done on a prototyping dSPACE DS1103 control system for an experimental 50 kW induction motor experimental stand. The prototyping system programming was done in the MATLAB/Simulink environment. Given that the control algorithm is intended to be used in an industrial system, the control model must be suitable to be converted into production code. Therefore, the study aims to overcome the limitations of industrial DSP systems for rotor field-oriented drive systems with induction motors.
