Control System Design for a Surface Effect Ship by Linear-Quadratic Regulator Method

In this paper, the main goal is to reduce the heave motion between a surface effect ship (SES) and a wind turbine in order to safely transfer equipment and person to SES. For this purpose, an LQR control system is designed to damp the vertical motion of the surface effect ship in critical sea states including high-frequency and high amplitude regular waves as well as high frequency irregular wa...

Robust Anti-Windup Controller Synthesis: A Mixed H2/H∞ Setting

In this paper an approach for robust anti-windup compensation design for multivariable controllers based on the characterization of H2-H∞ norms as Linear Matrix Inequalities (LMI) is presented. The method consider a mix of H2-H∞ performance indexes on the transfer functions of the disturbances to the controlled output, and of the actuator output signal to the controller output signal. The contr...

Mixed Sensitivity H Control of a Three-Tank-System

-A mixed sensitivity H control methodology is tested on a Three-Tank-System laboratory prototype. The methodology is based on a stable precompensator and its dual post-compensator which allows to solve a mixed sensitivity problem. Frequency responses show that it is possible to shape the open loop transfer function by the control parameters. Time responses are given under flow leak, close conne...

Robust convex lateral feedback control synthesis for a BWB aircraft

This paper presents the robust multi-objective design of a lateral feedback control law for a large flexible blended wing body (BWB) type passenger aircraft. An initial controller is synthesized and optimized using a convex synthesis approach based on the Youla parameterization and an LMI formulation. A multitude of both timeand frequency-domain design constraints are considered aiming to impro...
