Abstract A review presents the state-of-the-art path-following control systems for maritime autonomous surface ships, where special focus is placed on guidance subsystem and subsystem. The path following system one of basic requirements ships since it guarantees that ship can track predefined with small cross-track errors. problem firstly defined, error dynamics are derived from kinematic equat...

In this work, a sliding-mode-based attitude controller constrained with the angular rate for unmanned aerial vehicles (UAVs) is addressed to withstand conditions below allowable maximum velocity of UAVs in order avoid possibility structural failure and operate safely. The sliding mode suggested work defines new surface, inherently having two equilibrium points. These points are carefully inspec...

The path following is the automatic control of the mobile robot along the specified path without human interference. The proposed path following applies for the robot navigation in unknown environments, where the robot has no preliminary information about obstacles. This paper presents an innovative idea for the path following control that is to integrate the basic path following control with t...
