This paper investigates 2 difficult problems encountered in magnetic levitation systems: robust control design and disturbance rejection. A PI-PDN robust control strategy is developed to control the position of a 1-degree-of-freedom (DOF) magnetic le

This article proposes a novel gain scheduled control technique for a class of linear parameter varying (LPV) systems with main emphasis on reducing the cross coupling interaction in dynamics using the Hadamard weight. By employing the Hadamard and th

This paper presents two degrees-of-freedom (2-DOF) modeling of a lab aircraft extending corresponding author’s previous work on 1-DOF. The yaw motion is an additional DOF introduced along with the earlier work on pitch plane alone. The test-rig is

The control performance of aerial vehicles can be easily affected by measurement error in sensor output, dynamic model error, model parameter variation, parametric uncertainty, external disturbance, and dynamic coupling. This article presents a desig

This paper proposes an improved input shaping scheme for an efficient sway control of a nonlinear three dimensional (3D) overhead crane with friction using the particle swarm optimization (PSO) algorithm. Using this approach, a higher payload sway re
