The Key Technologies Research and Implementation of Hardware-in-the-Loop Simulation Based on Real-Time Environment
2018
This paper builds a typical HILS system based on the xPC real-time simulation platform and designs the key function modules of HILS by C++. A digital model of actual three-phase asynchronous motor speed control system is built and the parameters of the controller are optimized with the simplex algorithm. The optimized control parameters were applied to the HILS real-time control strategy model and downloaded to the HILS target machine. The A/D and D/A conversion was realized through the hardware I/O board, realizing the real-time simulation of the actual motor speed control system. By comparing the digital simulation results with the HIL real-time simulation data and curve images, the accuracy and effectiveness of the designed HILS system are verified.
