    Abstract:

    The linear maglev synchronous motor (LMSSM) which drives the maglev platform is controlled by TS model-based fuzzy control. The structure and operation mechanism of LMSSM are studied, and the mathematical model of LMSSM is established, including voltage equation, thrust equation and motion equation. Because the mathematical model of LMSSM has the characteristics of uncertainty, the TS fuzzy control is adopted, in which the speed error e and the change rate of speed error ec are selected as the input language variables, the triangle membership function with high sensitivity is adopted when the error is large. The trapezoidal function is adopted when the error approaches zero, and the linear combination of functions is adopted as the output of the fuzzy controller. According to the characteristics of the object, four fuzzy control rules are extracted. The designed controller is simulated by MATLAB software, and the results show that the controller has less rules. The control system has fast response speed and good anti-interference performance.
