The effects of mounting structure stiffness on mechano-hydraulic servomechanisms actuating aircraft primary flight controls are modeled by a six-dimensional nonlinear system of ordinary differential equations. Stability analysis of equilibria reveals

The backstepping technique is one of the tools which provides control Lyapunov functions (CLFs) and, therefore, control laws for automatic systems. In this paper, the backstepping design for position and force nonlinear electrohydraulic servos is inv

Starting from plysical laws a four-dimensional nonlinear model for mecano-hydraulic servomechanisms is deduced. The stability of its equilibria is analysed using a theorem of Lyapunov and Malkin to handle the critical case due to the presence of zero

The robust control of a general servomechanism problem is applied in the case of electrohydraulic servo actuating primary flight controls. The servocompensator structure is proved to be close to the one designed for step signals. The stabilizing comp

A pointing control system, combining passive inertial stabilization with active control, is presented. Such systems can direct an apparatus towards a fixed or slow moving target from a moving vehicle whose motion is almost rectilinear. The system was

This paper is concerned with the synthesis of control laws for semiactive suspension systems employing artificial intelligence. A review is made of a simple, 2-degree-of-freedom, quarter car model with passive, active, and semiactive control. An acti
