In this paper, the modified optimal sliding mode control with a proposed method to design a sliding surface is presented. Because of the inability of the previous approach of the sliding mode method to design a bounded and suitable input, the new variation is proposed in the sliding manifold to obviate problems in a structural system. Although the sliding mode control is a powerful method to re...

A blended autopilot algorithm is developed using generalized predictive control and adaptive non-singular terminal sliding mode control, for dual control missile steered by combination of aerodynamic fins and reaction jets. The blended algorithm considers the reaction jets control design prior due to its inherent control error, and then treats the aerodynamic fin control on the basis of the rea...

Most Fuzzy Controlers (FCs) for nonlinear 2nd order systems are designed with a two-dimensional phase plane in mind. We show that the performance and the robustness of this kind of FCs stems from their property of driving the system into the so-called sliding mode (SM) in which the controlled system is invariant to parameter fluctuations and disturbances. Additionally, the continuous distributi...

The bridge crane system is a typical under-actuated that widely used in production and life. Although various scholars have conducted extensive research on the recent years, there are still many problems, such as trajectory planning of cart anti-sway control cargo. In order to tackle problem cargo, hierarchical global fast terminal sliding-mode (H-GFTSMC) developed this work. First, Lagrange eq...

This study investigates the speed control of permanent magnet synchronous motors in presence external load disturbances via fast terminal sliding-mode (FTSMC). First, to enhance tracking performance, a logarithmic FTSMC method based on novel sliding surface is proposed improve previously introduced FTSMC. Second, we have derived an enhanced settling time, demonstrating its superiority over that...
