On the Rejection of Random Perturbations and the Tracking of Random References in a Quadrotor

Jesus Alberto Meda-Campana et al.

Summary: In this note, the problem of tracking random references and rejecting random perturbations in a quadrotor is solved by extending the deterministic tracking problem to stochastic processes. A controller is developed by combining a Kalman filter and an observer to estimate the references, perturbations, and states, which confirms its validity and effectiveness through numerical simulations.

Prescribed time tracking control of constrained Euler-Lagrange systems: An adaptive proportional-integral solution

Qian Cui et al.

Summary: This article investigates the problem of prescribed time tracking control for EL systems with modeling uncertainties, prescribed performance requirements, and time-varying state constraints. Two proportional-integral-like control schemes with time-varying gains are developed, ensuring prescribed tracking precision, state constraints adherence, preassigned tracking accuracy, and setting time, along with simple structure and inexpensive online computation. The proposed control's benefits and effectiveness are validated through numerical simulation.

Trajectory Tracking Control of Multi-DOF Robot without Considering System Dynamics

Saad Jamshed Abbasi et al.

Summary: In this study, two different control logics, sliding mode control with a sliding perturbation observer (SMCSPO) and integral sliding mode control (ISMC), have been designed for the position control of a robot with five degrees of freedom (DOFs). Both control schemes have been implemented in MATLAB/Simulink, and it has been observed that the ISMC controller has improved the tracking performance of the system.

A Nonlinear Observer for Robust Fault Reconstruction in One-Sided Lipschitz and Quadratically Inner-Bounded Nonlinear Descriptor Systems

Joseph Chang Lun Chan et al.

Summary: This article introduces a nonlinear observer for reconstructing faults in a class of nonlinear descriptor systems affected by disturbances. By transforming the original system and designing a nonlinear observer based on the transformed system, the gains of the observer are determined using linear matrix inequalities to bound the effect of disturbances on fault reconstruction. Three simulation examples are carried out to verify the effectiveness of the scheme.

Robust Impulsive Observer-Based Stabilization for Uncertain Nonlinear Systems With Sampled-Output

Oscar Jaramillo et al.

Summary: In this study, an impulsive observer-based control design for a class of nonlinear systems with time-varying uncertainties is proposed based on the LMI framework, with the use of local Lipschitz conditions. By utilizing sampled measurements of the system output and a time-varying Lyapunov function, sufficient conditions for the existence of the control are provided. Feasible solutions of the LMIs proposed are used to determine the observer and controller gain, showing that the approach effectively estimates and stabilizes all states both mathematically and through simulation.

Wei Hao et al.

Summary: This paper presents a robust tracking control strategy for three-rotor UAV, dividing the dynamic model into outer and inner loops and utilizing feedback linearization and RISE method. The stability of the closed loop system and the asymptotical tracking of the desired trajectory are proved via Lyapunov based stability analysis.
