In this paper, an accurate model of an airbrake electro-hydraulic smart actuator is obtained by physical considerations, and then different control strategies (variable-gain proportional control, PT1 control with switching integrator, and second order sub-optimal sliding mode control) are proposed and analyzed. This application is innovative in the avionic field, and is one of the first attempts to realize a fly-by-wire system for airbrakes, oriented to its immediate employment and installation on current aircraft. The project was carried on with the participation of the Italian Ministry of Defense, and was commissioned to MAG, a leading provider of integrated systems and aviation services for aerospace.

Active Unbalance Control of Rotor Systems Using On‐Line Algebraic Identification Methods
TL;DR: In this paper, an active control scheme based on compensation of perturbation force signals is proposed to balance rotating machinery with unknown system parameters and variable operation speed, where an algebraic parameter identification methodology is applied to estimate the mass, stiffness, damping, rotor eccentricity, and on-line reconstruction of the unknown centrifugal forces induced by rotor unbalance.

Observer-based sliding mode control of hydraulic cylinders in the presence of unknown load forces
TL;DR: An observer-based control scheme is proposed to regulate the position of the actuating cylinder that relies on on-line identification of unknown parameter as well as reconstruction and compensation of unknown load forces, such that the performance of the closed position feedback loop is superior compared to classical control strategies.

Chattering avoidance by second-order sliding mode control
TL;DR: A new solution to the problem of chattering elimination in variable structure control (VSC) is presented, inspired by the classical bang-bang optimal control strategy, and extended to the case of nonlinear systems with uncertainties of more general types.

Higher order sliding modes
TL;DR: So-called sliding modes are introduced, which become main operation modes in the variable structure systems (VSS) and reveal their main drawback: the so-called chattering effect, i.e., dangerous high-frequency vibrations of the controlled system.
