Abstract:Based on screw theory,the kinematics characteristics of 3DOF parallel manipulator was analyzed,and its mechanism model was also established by SolidWorks software.By using the model transformation interface technology,the visualization model of 3UPU parallel manipulator in SimMechanics was achieved.Furthermore,the fuzzy PID control system was designed.Combined the control system with the visualization model of 3UPU parallel manipulator,the system simulation was achieved.Compared with conventional PID control,simulation results shows that fuzzy PID control system of 3UPU parallel manipulator has advantages about high control accuracy,faster response,and good dynamic performance and so on.The studies of visualization and control system are valuable for theoretical research of lowDOF 〖BF〗mine’s〖BFQ〗 parallel manipulator.
