Development tool enables energy-efficient electric powertrains
dSpace has developed a software connection that allows complex control algorithms for frequency converters and electrical drives for vehicles to be developed and tested. This product is designed to be combined with the MicroAutoBox III prototyping system and the DS1553 Interface Module and extends their functional range.

The AC Motor Control Solution offers a comprehensive library of I/O functions. These represent the driver functions optimised for inverter control development via an easily configurable user interface. The functions can thus be graphically linked to the appropriate controllers, based on Matlab/Simulink, for example, using drag & drop. Further I/O functions exist for discrete signals and various position and rotary encoders. This expands the system's range of application, as protocol-based encoders are also supported. In addition to vehicles, example applications can also be found in highly automated industrial plants or in harvesters, in which low-cost electric motors are increasingly replacing complex and rigidly coupled mechanical drives. 

A key requirement in the development of the AC Motor Control (ACMC) Solution for MicroAutoBox III was full compatibility with existing hardware and software components from dSpace. In this way, a DS1553 AC Motor Control Module already available from MicroAutoBox II can continue to be used in the corresponding MicroAutoBox III. A change to MicroAutoBox III with its higher computing power and its new I/O modules such as the DS1521 Bus Board is thus supported in the best possible way.

The DS1553 is coupled to the Xilinx FPGA of MicroAutoBox. The I/O functions of MicroAutoBox III AC Motor Control Solution are based on the existing dSpace libraries developed for direct FPGA programming.

Typical applications for the AC Motor Control Solution for MicroAutoBox III include the development of drive controls and the development of mechatronic components such as steering systems or DC/DC converters, which are necessary for merging HV and LV vehicle electrical systems.
