Heavy lift crane vessels play an important role in offshore installations. Previous studies have shown that position control systems for these vessels can cause unstable positioning behavior during offshore construction assignments under specific conditions, e.g., change of environmental loads. Some control methods, such as crane force feedforward to the controller or the estimator, have been developed...
We present a distributed particle filter for bearings-only tracking of a target moving on the surface of a sphere, such as Earth. The proposed filter accounts for the curvature of the surface in the measurement model for more robust performance. In addition, a linearization of the likelihood function significantly reduces the communication overhead. Simulations demonstrate that the proposed distributed...
Power hardware-in-the-loop (PHIL) simulation is an advanced testing method with flexibility and fidelity. A PHIL system connects power hardware or physical models under test to a real-time simulator through an interface. This paper studies the basic and general theoretic analysis of PHIL simulation. Work timing, the base of PHIL simulation, is focused and studied in detail. Based on the timing, focusing...
An extended evaluation method for the decision-making problems of alternatives is introsuced by means of extension theory. The extended evaluation method can carry out the decision-making problems of the alternatives based on matter-element models and extended relational degrees. The matter-element model of the desired alternative (ideal alternative) and the matter-element models of alternatives are...
Aim to the intelligentized aid industrial design method based on product semantics, bring forwards the vague expression way of product semantics, discuss the technique to get the product semantics by tests, founds the product multidimensional semantics space and the industrial design method based on it, establish a framework of CAIDS which is based on product semantics-aided.
This paper presents the mathematical models and computer simulation for the power system of Yantai-Dalian train ferry. Firstly the system configuration is illustrated and then the mathematical models of main components are presented. Finally three typical dynamic operating scenarios are investigated through the computer simulations with Simulink. From the simulations, it is found that the machines...
This paper investigates the EKI phenomenon in a double T-shaped microchannel, in which two aqueous electrolyte solutions with a 3.5:1 conductivity ratio are driven electrokinetically into the mixing channel via the application of a DC electrical field. A stratified flow condition is formed when the intensity of the applied DC electrical field is below a certain threshold value. However, as the intensity...
