Abstract:

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 waves. The simulation results show the high quality of the system control in the studied sea condition.  A comparative analysis of LQR and PID approaches demonstrate the high performance of the new designed control system. The proposed controller outperforms the traditional PD.

Iterative Linear Quadratic Regulator Design for Nonlinear Biological Movement Systems

This paper presents an Iterative Linear Quadratic Regulator (ILQR) method for locally-optimal feedback control of nonlinear dynamical systems. The method is applied to a musculo-skeletal arm model with 10 state dimensions and 6 controls, and is used to compute energy-optimal reaching movements. Numerical comparisons with three existing methods demonstrate that the new method converges substanti...

A reasoning method for a ship design expert system

The ship design process is a highly data-oriented, dynamic, iterative and multi-stage algorithm. It utilizes multiple abstraction levels and concurrent engineering techniques. Specialized techniques for knowledge acquisition, knowledge representation and reasoning must be developed to solve these problems for a ship design expert system. Consequently, very few attempts have been made to model t...

Linear quadratic regulator controller design for active suspension system subjected to random road surfaces

Present work aims at developing an active suspension for a passenger car by designing a controller using linear quadratic optimal control theory, based on two different control approaches [conventional method (CM), acceleration dependent method (ADM)]. Performance of the active suspension system of a quarter car model with 3 degrees-of-freedom with two control approaches has been compared with ...

Design of a Linear Quadratic Optimal Control for Aircraft Flight Control by Genetic Algorithm

In this paper we have investigated the use of genetic algorithm for the selection of weighting matrices of performance index for the linear quadratic control design. We can easily consider in the fitness index of the genetic algorithm different design specifications and their verifications in different operations conditions. As well as a measure of robustness σ(S+T) evaluated at the input and a...
