On the test platform of electric power steering systems, the control of AC servo motors was implemented by Matlab/Simulink and xPC. Based on the establishment of the lower-cost simulation system of double PC, the driving program for the PCI-1720 data card on xPC target toolboxs was developed. The experiment circuits were connected and the loading experiment of AC servo motors was carried out on the electric power steering test platform. The result shows that, the loading torque of AC servo motors under the control of xPC can change with the rota- ting angle, which meets the test goal of controlling the load of AC servo motors through double PC. The application range of xPC target toolbox is extended through the development of xPC driving program, and the communication between Matlab and hardware were enhanced.
