为提高空中交通流量,减少人为因素对航空安全的不利影响,必须逐步实现空中交通管制自动化。研究了空中交通管制和飞行控制共同作用的航班进港过程的系统属性;提出将由离散事件系统和物理系统组合的混合系统简化为动态系统综合分析,用成熟的滑模变结构控制理论设计安全可靠的航班进港系统。为减小人为因素和环境条件变化引起过程参数摄动的影响,提高受控系统的鲁棒性,设计了离散滑动模态变结构控制器。进一步考虑民航飞机加减速和机动能力的限制,在控制器设计中将其作为约束加以考虑,并分析了约束大小的影响和对过程参数变化的适应性。计算表明闭环系统在过程参数较大范围变化时,能保证系统有良好的稳定性和由变结构控制设计所给定的动态特性。结合进港具体过程,为空中交通管制实现自动化提出可实施的技术方案。 相似文献

The authors discuss two knowledge-based systems that are currently under development by the US Federal Aviation Administration, namely a simulation system for air traffic controller training and an automated problem resolution capability that is the central feature of the Automated En Route Air Traffic Control System (AERA 2). For each of these systems, the manner in which knowledge-based system technology is applied is discussed, along with the knowledge bases. The process for building, refining, and evaluating the knowledge bases is also presented. In the air traffic controller training system, ATCoach, the representation of ATC knowledge has been shown to be highly beneficial for both ATC training and airspace modeling. In AERA 2 automated problem resolution (APR) evaluations, the AI/knowledge-based system technology has proven to be indispensable in the representation of the experts' knowledge and the effective factoring of the knowledge into APR. It is concluded that these applications offer great potential for success and, consequently, represent only the first step in applying AI principles to ATC 相似文献

The yearly average number of airliners reported, worldwide, as having been involved in a mid-air collision is less than two. Air traffic control (ATC) aims to hold this rate, despite future traffic growth. Improvements in air-ground communications, e.g. by the use of selectively addressed secondary surveillance radar (SSR Mode S), make possible surveillance of the air situation by ATC computers, thus trapping potentially dangerous discrepancies between ATC plans and reality. The necessary level of confidence makes it unlikely that computers will soon take over from human pilots or controllers. However, as computers are prone to different errors than those of humans there is a good case for mechanised redundancy to assist ATC decision taking 相似文献

Although established some 60 years ago voice communications is still the sole means to separate and guide aircrafts. Voice communication systems are therefore amongst the most critical installations in air traffic control (ATC). Frequentis was the first to introduce PCM (pulse code modulated) based equipment for ATC worldwide and is on the leading edge of steering into the world of packetized voice communications. VoIP is the emerging voice communication technology which has already proven to provide satisfactory service for commercial applications. However, in ATC a number of requirements exceeding commercial applications have to be met. The voice communication system for ATC integrates radio communication as a prime service. Delays generated by the system therefore directly affect the performance on the radio channel and need to be extremly low. Both the radio control (push-to-talk, PTT) and the voice content need to be processed and delivered in a timely manner. SIP (session initiated protocol) based signalling represents a promising approach to tackle the delay problem. In addition, voice communication systems are required to provide high availability figures. VoIP based systems strongly rely on the communications infrastructure as they are distributed by nature. Resilient packet ring structures allow for these high availablity figures for the communications infrastructure. 相似文献

This paper is designed as a survey document to be used as an overview and introduction to the various concepts and levels of complexity of current and future aids to air navigation. Major emphasis will be placed on identifying those technical and operational characteristics of each system concept and/or mechanization that have a significant impact upon both cockpit and ground-based communications and data processing. A representative bibliography is included to provide the reader the ability to pursue the subject further from an operational as well as a technical viewpoint. The object of this paper is to identify the relationship of air navigation aids to the flow and utilization of information in air navigation and air traffic control (ATC). Air navigation aids vary widely in both complexity and performance capability and these factors have a significant impact upon communications, data processing, and display, both in the air and on the ground. 相似文献
