Summary: This paper discusses the observer-based trajectory control of directional drilling system with rotary steering devices. It establishes a trajectory control approach using a state observer to estimate the trajectory orientation based on the measurement of the BHA orientation. The paper analyzes the relationship between the trajectory orientation and the BHA orientation, formulates a trajectory tracking control problem, devises a feedback control strategy, discusses stability analysis, and showcases correctness and effectiveness through a typical case scenario.

Summary: This paper rigorously investigates the problem of active disturbance rejection control for nonlinear systems subject to uncertainties and dead-zone input. Utilizing an extended state observer (ESO) and a switched dynamic parameter estimation law, the paper separates the dead-zone model from the total uncertainty and estimates the parameters of dead-zone online. The theoretical analysis of stability shows that the closed-loop system has multi-time scale convergence properties.

Summary: The paper introduces the output feedback stabilization of a first-order hyperbolic equation with multi-point nonlocal term by boundary control. A boundary state feedback controller is designed using the backstepping method, ensuring exponential stability and constructing output feedback control based on an infinite-dimensional observer. The resulting closed-loop system is proven to be exponentially stable using operator semigroup theory, and the validity of the proposed controller is demonstrated through numerical simulations.

Summary: This article investigates the vibration and disturbance rejection problem of a wind turbine tower under external perturbations. The tower dynamics is described by a nonhomogeneous Euler-Bernoulli beam model, and the dissipativity of the system is achieved through a boundary feedback control solution. A Lyapunov-based stability analysis is conducted to demonstrate that the deflection of the tower remains uniformly bounded even in the presence of external disturbances. The extended Filippov framework and Galerkin approximation scheme are utilized to handle the existence of solutions to the system with a discontinuous control input. Simulation results show the effectiveness of the proposed control scheme.

Sufficient conditions for the existence of the proposed observer-based fuzzy controller are developed for ensuring the exponential stability of the augmented closed-loop system, and a local algorithm for solving the bilinear matrix inequalities is proposed. Numerical simulation results are provided to support the proposed design method.

Summary: In this article, the robust output regulation problem of linear systems is studied using an event-triggered output feedback control law, which is implemented through an output-based triggering mechanism. The solvability of the problem is summarized by internal model design, and it is shown that solving the problem with an event-triggered control law does not lead to the Zeno phenomenon and prevents the interevent time from approaching zero as time tends to infinity.
