This study explores the control of a space capsule during the re-entry phase. Spacecraft re-entry is a critical phase of a mission because, as the spacecraft enters Earth's atmosphere, aerodynamic forces and moments can disturb the angles of attack a

To create drag and reduce the speed of space payloads in the phase of entering the atmosphere, the payload body itself can be used as brake mechanisms without using additional tools. The approach analyzed in this paper is the separation of the nose a

PurposeThis study aims to minimize the risk of costly failures of flight tests during the path tracking control design, and a noble approach has been proposed in this study to put the whole vehicle-in-the simulation loop. Working with the real system

This paper addresses the attitude path design of a remote sensing satellite in various imaging modes. The novel path design algorithm is based on local polynomial regression, which produces a smooth attitude path by receiving the size and timing of m

This work presents a novel geometric framework for self-balancing as well as planar motion control of wheeled vehicles with two fewer control inputs than the configuration variables. For self-balancing control, we shape the kinetic energy in such a w

This paper studies the problem of set-point stabilisation, trajectory tracking, and formation tracking for unicycle-type vehicles by taking advantage of the exponential coordinates and the other mathematical tools provided by the Lie group setting of

This paper addresses the problem of consensus and formation control for nonholonomic multivehicle systems. The problem is formulated using the definition of the convex combination on SE(2) which simultaneously preserves the nonholonomic constraint in

This paper presents a novel concept of a co-axial bi-rotor UAV which is controlled by moving its center of gravity. After deriving a 6DOF nonlinear model using the Euler-Newton method, we introduce a simplified 3DOF model for planar motion. Due to th

This work presents a controlled Lagrangian for the wheeled inverted pendulum system in which the upward position of the pendulum becomes a stable nonlinear equilibrium. Unlike the general form of underactuated systems, the configuration variables are
