Abstract: It was difficult to perform the force position control on the numerical control system, and the parameter adjustment was complicated. To deal with these problems, a hardware-in-loop simulation system was developed based on Q8 card and Simulink module. By taking X-Y-Z three-axis motion platform as the control object, the components of hardware & software of the system were designed. To obtain the constant force control of the Z-axis, the controller with the position loop and the force loop were designed in the Simulink software. The actual simulation curve was also presented. Results showed that the presented controller was with reasonable design, easy parameter adjustment and intuitive actual effects.
