The real-time simulation system developed on xPC platform depends on MATLAB commonly, and it affects its application in engineering. Aiming at this problem, a method of designing simulation system based on xPC Target and LabWindows/CVI is presented. Simulation systems designed in this method, not only realize independent host PC programs, but also can take full advantages of professional virtual instrument provided by LabWindows/CVI to develop the main console simulation software. Simulation proves that the system can achieve real-time simulations with sample time lms,data updating cycle lms and display updating cycle 10ms. The simulation system has a friendly interface, high real time property and operates easily, which provides beneficial reference for the real-time simulation system on xPC platform in practical engineering application.
