Abstract

This paper proposes a Disturbance-Compensated Non-Singular Fast Terminal Sliding Mode Control (DC-NFTSMC) method to address the issues of slow convergence speed and poor robustness in traditional turntable control methods. By designing an improved non-singular fast terminal sliding mode surface and reaching law, the convergence speed of the turntable system is significantly enhanced. Additionally, an Extended State Observer (ESO) is incorporated to estimate and compensate for complex disturbances and improving the robustness of the turntable system. Simulation results demonstrate that, compared with traditional methods, this control method not only effectively improves the tracking response speed of the turntable system but also ensures superior robustness in the presence of multiple superimposed disturbances.
