Zusammenfassung: | Terminal sliding-mode (TSM) control (TSMC) is known for its high gain property nearby the vicinity of the equilibrium while retaining reasonably low gain elsewhere. This is desirable in digital implementation where the limited sampling frequency may incur chattering if the controller gain is overly high. In this paper, we integrate a linear switching surface with a terminal switching surface. The switching surface can be designed according to the precision requirement, and for the first time, real-time implementation of TSM is carried out. The analysis and experimental investigation show that the TSMC design outperforms the linear sliding-mode control. |
