Design of High-Speed Signal Simulation and Acquisition System for Power Machinery Virtual Testing

The rapid advancement of model-based simulation has driven the increased adoption of virtual testing in power machinery, raising demands for high accuracy and real-time signal processing. This study introduces a real-time signal simulation and acquisition system leveraging field-programmable gate array (FPGA) technology, designed with flexible scalability and seamless integration with NI hardware-based test systems. The system supports various dynamic signals, including position, injection, and ignition signals, providing robust support for virtual testing and calibration. Comprehensive testing across scenarios involving oscilloscopes, signal generators, and the rapid control prototyping (RCP) platform confirms its high accuracy, stability, and adaptability in multi-signal processing and real-time response. This system is a state-of-the-art and extensively virtual field-tested platform for both power systems and power electronics.
