TL;DR: In this article, the problem of the design and implementation of a two-axis sun tracking system was addressed by applying a set of two robotic systems, one for the automatic orientation of the photovoltaic modules and the second for providing the reference trajectory (robotic sensor).

TL;DR: The design and experimental assessment of feedback linearization and sliding mode control techniques to the tracking trajectory problem of a flexible-joint robotic arm for a smooth rest to rest maneuver show the improvements and effectiveness of the proposed control laws in disturbance rejection tasks.

TL;DR: The main purpose is the behavior modification of the system through the combination of two manipulation strategies, one associated with the energy savings and the other with the tracking error, to significantly reduce energy consumption while concurrently achieving a competitive tracking error.

TL;DR: This paper presents a control algorithm for the taking off and landing manoeuvres of a quadrotor aircraft in open navigation environments, using a combination of controllers based on nested saturations and a generalised proportional integral (GPI) controller.

TL;DR: The aim of this study was to design and evaluate a prototype of a snake-like endoscopic manipulator robot (SLEMR) and its corresponding automatic controller based on the first order sliding mode theory and it was confirmed by the evaluation of the tracking error of the final actuator.
