Abstract: Traditional control system research is based on the analysis of the step response control curve.In view of this,a more effective and intuitive comparative analysis method is proposed to analyze the control effect of different control algorithms(normal PID and fuzzy PID).The method of electromechanical co-simulation was adopted to building a virtual platform.When the mechanical model of SolidWorks was in motion,the Lab VIEW control platform could monitor the control effect of the control system in real time.The results show that through the co-simulation of LabVIEW and SolidWorks,not only the motion of three-dimensional model is controlled precisely by the control algorithm,but also the comparison of the motion effects of different algorithms is realized.The motion curve of the three-dimensional model shows intuitively that the fuzzy PID control system has less control response time and better motion speed stability.
