液化天然气(LNG)船液货装卸过程中,需严格控制装卸时间,但由于装卸系统的复杂性,设计装卸系统时很难准确得到LNG在管路中的流动状态平衡控制。针对上述问题,提出了一种面向LNG船液货装卸系统结构的计算方法,根据图论和有限元软件构建装卸系统拓扑模型,形成双层反馈控制结构,建立仿真装卸模型,计算任意时间点的管网节点压头和管路流量情况。采用Visual C++编制了图形化界面的仿真计算软件进行仿真。仿真结果与实际情况基本符合,表明装卸方法具有实用性,能对LNG船液货装卸系统的设计起借鉴作用。 相似文献

A fuzzy collaboration system was designed for ubiquitous loading/unloading space recommendation in the logistics industry. The designed system allows drivers to share information regarding the availability of loading/unloading spaces without providing the exact number of available loading/unloading spaces, thus promoting drivers to use the system. To derive the exact number of loading/unloading spaces from the inexact information, a quadratic programming problem was formulated and solved. In addition, driver location and speed were modeled using fuzzy numbers to account for the uncertainty of their locations. Subsequently, fuzzy cross-referencing was used so that loading/unloading space information can be referenced from more than one location. The proposed methodology was applied to a small region in Seatwen District, Taichung City, Taiwan. The designed system reduced the average time required for a driver to locate a nearby loading/unloading space by 72%. 相似文献

In recent years, the scale of container transportation and the size of vessels are becoming larger and larger; development of automatic container cranes becomes a necessity. As a key function of automatic control of unmanned cranes, the optimum route can minimize the cycle time by calculating the most efficient combination of horizontal and vertical motions of container loading/unloading. In this study, we have comprehensively studied various issues in the route planning in different fields. Later, the mathematical model based on the problem analysis of loading/unloading process was presented. Particularly, to solve the problem, an optimum route method based on genetic algorithm, which satisfies the criteria such as length, smooth degree and safety distance, was developed. Finally, the computational experiments testified the effectiveness of the algorithm and explored a new way to increase the efficiency of container loading/unloading process. 相似文献

In this paper, we intend to show the basis of a general legged locomotion controller with the ability to integrate both posture and rhythmic motion controls and shift continuously from one control method to the other according to the walking speed. The rhythmic motion of each leg in the sagittal plane is generated by a single leg controller which controls the swing-to-stance and stance-to-swing phase transitions using respectively leg loading and unloading information. Since rolling motion induced by inverted pendulum motion during the two-legged stance phases results in the transfer of the load between the contralateral legs, leg loading/unloading involves posture information in the frontal plane. As a result of the phase modulations based on leg loading/unloading, rhythmic motion of each leg is achieved and inter-leg coordination (resulting in a gait) emerges, even without explicit coordination amongst the leg controllers, allowing to realize dynamic walking in the low- to medium-speed range. We show that the proposed method has resistance ability against lateral perturbations to some extent, but that an additional ascending coordination mechanism between ipsilateral legs is necessary to withstand perturbations decreasing the rolling motion amplitude. Even without stepping reflex using vestibular information, our control system, relying on phase modulations based on leg loading/unloading and the ascending coordination mechanism between ipsilateral legs, enables low speed dynamic walking on uneven terrain with long cyclic period, which was not realized in our former studies.
