H ∞ control design to include nonlinearities. Second report: nonlinearities in equations of motion

Autor: Hiroyuki Yamato, Takeo Koyama, Fengyang Tan

Publikováno v: Journal of Marine Science and Technology. 6:148-157

In our first report, a method to deal with the nonlinearity of saturation was proposed. A method of dealing with nonlinearity in equations of motion is proposed in this paper. The nonlinear equations of motion are expressed as variations of linear eq

An Unified Longitudinal Control System for Hydrofoil Based on Wave Prediction

Autor: Hiroyuki Yamato, Akira Fushimi, Sang-hyun Kim, Takeo Koyama

Publikováno v: IFAC Proceedings Volumes. 31:223-228

Hydrofoil longitudinal control has been made by mode selection between platforming and contouring. In addition, the height control has been made by wave observation by human operators. To exclude this human operation, the unified automatic control sy

An Examination about the Hub-Spokes Type Transport Form

Autor: Hisayuki Kurokawa, Takeo Koyama, Hiroyuki Yamato

Publikováno v: Journal of the Society of Naval Architects of Japan. 1998:617-625

There is a transport form of the multiple seed multiple states of freight transport in such cases as the Hub-Spokes type transport, the direct delivery type transport between two points, the round type transport. In this, do an examination about the

A Design of the Container Cargo Flow Network Based on the Mathematical Programming

Autor: Hiroyuki Yamato, Tomohiro Tsunoda, Akira Fushimi, Takeo Koyama

Publikováno v: Journal of the Society of Naval Architects of Japan. 1998:607-615

The container cargo flow is now growing, especially in Asia. Coping with this growth, the size of container ships become bigger and the container cargo flow network is changing to, for example, hub and spokes network. The present paper proposes a des

A Study on Unified Automatic Control System for Longitudinal Motion of Jetfoil Based on Optimal Servo Theory

Autor: Akira Fushimi, Hiroyuki Yamato, Takeo Koyama, Sang-hyun Kim

Publikováno v: Journal of the Society of Naval Architects of Japan. 1997:241-247

Current Jetfoil control has been made by platform and contour mode selection and by manual input of fore-foil depth according to sea conditions by human operator, which cause overload and may be difficult for operators. This requires the further auto

An Approach to Knowledge Acquisition for the Hull Form Design of Fishing Crafts

Autor: Hiroyuki Yamato, Glenn Aguilar, Takeo Koyama

Publikováno v: Journal of the Society of Naval Architects of Japan. 1996:213-222

The problem of acquiring procedural knowledge for hull form design and construction of a knowledge base for hull form selection is addressed in this paper. An object oriented methodology involving creating classes, state diagrams and data flows for p

Sliding Mode Control for Ride Control System of SES

Autor: Takeo Koyama, Shin Ueda, Hiroyuki Yamato

Publikováno v: Journal of the Society of Naval Architects of Japan. 1996:669-676

The Surface Effect Ship (SES) has very good speed performance and ride quality in the calm sea. However, in case of rough seas, it may deteriorate its performance due to the air leak from the gap between the hull and water surface. The ship is equipp
