Abstract: Robust control for linear motor (LM) is essential in a mechatronic system where rapid response and high accuracy are requested. This research elaborates the design of robust control approach employing a second-order terminal sliding mode control (2OTSMC) strategy integrated with an online perturbation estimation (PE) technique, namely 2OTSMCPE for an LM system. The proposed control architecture can provide high accuracy in terms of tracking LM performance in nominal and uncertain models. Moreover, adopting PE has facilitated control design and simplified its practical applications. Since there is no need for upper bound system perturbation in the 2OTSMCPE control design, no significant effort is required for control, which avoids the overestimation issue. Furthermore, for optimum performance, we have given a guideline to the parameter's selection of the proposed controller. Finally, simulations studies have been conducted to demonstrate the validity of the 2OTSMCPE controller in terms of time response and tracking performance across the non-singular terminal sliding mode controller (NTSMC).
