Abstract The position tracking accuracy of permanent magnet linear synchronous motor (PMLSM) servo system is easily affected by uncertain factors, such as parameters change, load disturbance and friction and so on. Therefore, an adaptive backstepping global fast terminal sliding mode control (ABGFTSMC) method is proposed. Firstly, the PMLSM dynamic mathematical model with uncertainty is established. Then, the complex nonlinear system is decomposed into low order subsystems by the backstepping control, and the state of the system is rapidly converged to the equilibrium point by the global fast terminal sliding mode control, which can improve the response speed and robustness of the system. In order to obtain the appropriate switching gain, the chattering phenomenon is reduced by adjusting the gain value of the switching control with adaptive control in real time. It is proved theoretically that the control scheme can make the system obtain fast convergence and good tracking performance. Finally, the system experiments show that the proposed control scheme not only has faster convergence, but also has faster tracking and stronger robustness.
