Simulation Research of Self-adaptation Fuzzy-IMC Algorithm Based on Virtual-axis polishing Machine Tool

In view of the characteristics of virtual-axis polishing machine tool developed by our research team, an algorithm of self-adaptation fuzzy-IMC (internal model control) is proposed. This algorithm can compensate dynamically for the effect of external disturbance by using IMC. Self-adaptation fuzzy controller is regarded as the main controller, whose non-linearity and robustness are an aid to enhance the dynamic characteristics and robustness of system. The result of simulation demonstrates that this algorithm is more effective in restraining the coupling effect of each link of the virtual-axis polishing machine tool and external disturbance, which has more powerful robustness and enhances each performance target of system, by comparing with PID, IMC or fuzzy control
