项目摘要

1. Automatic pouring process is constructed of a pouring process injecting molten metal into a mold and also transfering a poring machine from a certain place to an another place. In the present researches, the above two problems have been studied among four reserchers working in universities institution (Terashima, Toyohashi University of Technology ; Maeda, Natoya University), casting machine builder (Yoshida, Fujiwa Electric Company) and Casting Production Maker (Osada, Osada Casting Company). The results obtained in this researches are the followings.2. With respect to pouring proces, modelling, simulation and control of an automatic pouring system of tilting-type considering the fluid behavior. A mathematical model is built usitn two dimensional continuity and Navier-stokes equations with the term of tank rotation. Model validity is confirmed by experiments. The effect of operated variables like the tank shape, the position of rotary shaft and the angular velocity of tank rotation is analyzed on the fluid behavior during pouring. Flow rate control and vibration control using preshaping theory guaranteeing the posotion control of tank angle are als given.3. With respect to transferring process, we proposed the liquid container transfer system with the robustness for the change of liquid level. H-infinity control theory has been applied to this system to obtain the robustness for the change of liquid level. Furthermore, a reference trajectory is reasonably determined by an optimization method of Fletcher Reefves combined with a clipping-off technique to suppress the sloshing (liquid vibration). Through simulations and experiments, the effectiveness of the present control system has been demonstrated.

1。自动浇注过程是由将熔融金属注入模具中的浇注过程构建的，还将孔孔机从某个地方传递到另一个地方。在目前的研究中，在大学机构（Terashima，Toerohashi Technology； Maeda，Natoya University），铸造机构建造者（Yoshida，Fujiwa Electric Company）和Casting Producting Maker（Osada，Osada Casting Company）中研究了以上两个问题。在这项研究中获得的结果是以下2。关于倒入过程，考虑流体行为的自动倾斜系统的建模，模拟和控制。构建了数学模型USITN二维连续性，并用储罐旋转术语构建了Navier-Stokes方程。模型有效性通过实验证实。在倒入过程中，分析了操作变量，例如储罐形状，旋转轴的位置和储罐旋转的角速度的影响。使用预塑性理论保证储罐角度控制的流速控制和振动控制为3。关于转移过程，我们提出了液体水平变化的鲁棒性，提出了液体容器转移系统。 h-侵权控制理论已应用于该系统，以获得液位变化的鲁棒性。此外，参考轨迹是通过弗莱彻·海湾（Fletcher Reefves）与剪裁技术相结合的优化方法合理确定的，以抑制晃动（液体振动）。通过模拟和实验，已经证明了当前控制系统的有效性。
