In this note, the second-order sliding-mode control problem is tackled by explicitly taking into account the presence of measurement error with unknown upper bound \delta. Under sensible assumptions regarding the uncertain dynamics of a broad class of nonlinear plants, a new switching controller is proposed guaranteeing a sliding accuracy of order (\delta). Simulations highlight the robustness and good performance of the proposed approach, and confirm the expected precision order.

Abstract
In this note, the second-order sliding-mode control problem is tackled by explicitly taking into account the presence of measurement error with unknown upper bound \delta. Under sensible assumptions regarding the uncertain dynamics of a broad class of nonlinear plants, a new switching controller is proposed guaranteeing a sliding accuracy of order (\delta). Simulations highlight the robustness and good performance of the proposed approach, and confirm the expected precision order.
