Expansion application of dSPACE for HILS

As an excellent implement used for controller development and HIL simulation, dSPACE has been applied to many fields. But it can not meet the demands of data processing and sampling in some complex or high-speed occasions. By making use of FPGA in this paper, the problems will be easily resolved. In accordance with the usual requirements, I/O expansion, PWM generator, A/D sampling preconditioning, and data processing modules were constructed as the basic function modules. The dSPACE real-time controlled object through the FPGA, and captured the data from the FPGApsilas collection. Experiments showed that this method could effectively compensate for the deficiencies in the traditional dSPACE application, and enhance the platformpsilas functions. More important was that this way could save the consumption of the dSPACE platform resources, improve the system frequency, and make the dSPACE systems to accomplish more complex HIL simulation.
