In this paper, the output regulation problem of linear multi-agent systems through one leader is considered. The overall system consists of a leader agent, which can access the exogenous signal, and the followers agents. The method considers a static feedback control law of the output agents and a robust control applied to the leader agent, allowing synchronization of the agents in the system. Finally,...
Chaotic dynamical systems are extremely sensitive to initial conditions and their behavior is unpredictable. On the other hand, in regulation theory, an exosystem is available when it's known; however, if it is unknown, it should be estimated with any adaptable recognition technique. This paper presents a perturbed chaotic oscillator by a unknown sinusoidal signal, in which the perturbed signal is...
A design procedure to robustly globally stabilize the Planar Vertical Take Off and Landing (PVTOL) around a position by means of bounded control law and without knowledge of the velocities is presented. The methodology is based on the use of saturation functions bounding the thrust and the roll inputs. To this purpose the techniques given in [13]-[14] (making use of the full state) are enriched with...
The synchronization of neuron networks using the contraction theory is reported in this contribution. The contraction theory provides a simple method to determine convergence of trajectories of the systems in the network instead of the Master Stability Function and the calculation of Lyapunov exponents. The objective is to determine the contraction region where once the trajectories reach such region...
In this contribution we present the mutual synchronization of an ensemble of robots with strictly different architecture. The main idea is to achieve synchronization in a group of robots composed by rotational-rotational and rotational-prismatic architecture. The synchronization is achieved into the workspace, this is, and the end position of each robot is equal to the rest of the robots. It implies...
We analyze the behavior of the diffraction efficiency as a function of the thickness of the relief holographic grating recorded on a phase emulsion composed by rosin and bromophenol blue (BPB) dye. The emulsions thicknesses are mainly due to the rosin quantity deposited on a substrate. We record holographic gratings on each emulsion using the spectral line λ=457nm of an argon laser, after this we...
In this note, we design and construct a globally convergent frequency estimator with analog electronics components, this electronic design is based on the scheme proposed in [1], the results are showed in simulation and also in real time; the design can be extended to the design of two or more frequencies.
