An Optimal Sliping Frequency Control Implementation for Induction Traction Motor on dSPACE 1104 DSP Board

摘要

The aim of this paper is the implementation of the control algorithm of an optimal sliping frequency control for induction traction motors using the dSPACE DS1104 prototyping board. The control system is tested on a comprehensive experimental setup, based on a drive motor of 3 kW. The control algorithm was previously validated on the drive system virtual Simulink model, with the same parameters as the experimental drive system, so the control system parameters have already been refined. At the same time, not only the control parameters are taken from the virtual system, but the whole control algorithm. This is because the executable program for the DS1104 prototyping board is obtained by compiling a Simulink model. So the experimental system control algorithm a section of the virtual drive system and consequently the experimental results are completely comparable with the initial virtual results. The complete control model is obtained by adding to the control subsystem the Real Time Interface blocks (necessary to make the link between the software (the Simulink model) and the DS1104 hardware (analog to digital converters, pulse width modulators, etc.). The power system is real time controlled by means of a virtual control panel linked to the control model blocks, parameters or signals.
