Programming Electric Drives
dSpace, the Wixom, Mich., provider of hardware and software tools for developing and testing electronic control systems recently released its XSG AC Motor Control (XSG = Xilinx System Generator) library software for developing control systems for electric drive applications in mild/full hybrid vehicles, electric vehicles, electromechanical (EMA) and electrohydraulic (EHA) actuators, drivetrain actuators, electronic servo steering and auxiliaries such as oil and water pumps.
The library is designed to enables engineers to program Field Programmable Gate Arrays (FPGA) for use in control tasks with dSpace MicroAutoBox II and Scalexio systems, as well as modular dSpace hardware. By moving control loops onto reconfigurable hardware, engineers can achieve execution speed of over 100 kHz and conveniently develop dynamic electric drive systems for applications demanding precise position and speed, the company said. The XSG AC Motor Control library allows for evaluation of various types of position sensors, including encoders, resolvers etc., as well as flexible generation of pulse width modulation (PWM) signals.
