Safety Risks

Purpose This study aims to optionally-piloted aircraft is useful for in-flight tests of new automatic controller’s concepts. The safety of this kind of experiment is an issue addressed in this paper. The prediction of possible safety-influencing factors makes it possible to assess the pilot’s ability to effectively prevent safety risks. Design/methodology/approach The analysis in this research paper focusses on two cases of monitoring; similar control standards for both pilot in command and the monitoring pilot or technical systems in one of these tasks and dissimilar control standard when monitoring pilot is not familiar with a control manner of the pilot in command or of the automatic control system. The increased workload is expected in the last case as the result of additional activities determined theoretically in the presented analysis. Details of the possible threats are obtained by simulation tests with various factors influencing the safety of landing. In addition to determining threats, the analysis includes the possibility of in time threat detection and preserving action. Findings The results show that the safety pilot has a different task than the pilot in command and needs to be familiar with the general principles of automatic controller operations and the particular algorithm being tested. Although commonly used landing procedure is relatively error-tolerant, new landing procedures for use in some specific conditions need more precise control and additional safety pilot preparation. Additional information presented to both the pilot in command and the safety pilot may increase mode and state awareness and reduce reaction time in an emergency condition. Practical implications In-flight tests of non-standard control algorithms there is a need to include additional preparation of the equipment and safety pilot. The research in this paper illustrates how to determine threats and safety-critical moments during the experimental flight can be observed. The danger is mitigated by the safety pilot, if familiar with both proper and improper operations of the controller and how the pilot in command should detect and predict danger caused by the tested control system. Originality/value The presented method of analysis combines the human factor with various technical aspects. The results obtained illustrate the real tasks of the person supervising the operation of the automatic control system and the role of a human as a safety pilot.

Alternative Principle

This article introduces the alternative principle of progressive characteristic of unbounded Jacobi matrix into the process of automatic control of circuit which makes the feedback signal of control circuit has two different delay characteristics using unbounded Jacobi matrix. It also adds the weight of transconductance unit. The voltage signal can output smoothly which reduces the oscillation of the circuit and improves the accuracy of the circuits automatic control. This paper studies the control role of unbounded Jacobi matrix on the circuit using experimental method and gets the I / V curve. From the curve, we can concludes that the I / V of the circuit is not constant. The boundaries of linear region and the saturation region correspond with unbounded Jacobi matrix theory. Linear and saturation regions have no obviously transition boundary which applies unbounded Jacobi matrix to the automatic process of circuits successfully.

This chapter presents a sequential approach to the introduction of e-learning in the field of automatic control as realized at the Faculty of Electrical Engineering, University of Ljubljana, Slovenia. However, the proposed methodology can easily be extended to other scientific fields. First, the organization of the lectures and the main activities are described. Then the motivational aspects for the reorganization are presented, where the design projects introduced during the exercises play an important role. As a result of the positive response to this approach, one of the projects was further extended and realized as a combination of exercises and exams, incorporating parts of a computer game and competition using virtual and remote experiments with a chosen multivariable pilot plant. The students’ responses and staff experiences are evaluated and analyzed, from which the potential advantages of the proposed approach become clear.

Working Medium

The working medium of the pneumatic control system is air, which is delivered to each branch pipe through the role of the governing valve , and then the divided gas delivers the compressed air to each solenoid valve and pneumatic control valve. The solenoid valves and pneumatic control valve is connected through terminals and PLC, PLC obtains corresponding signal and makes judgment, conveying signal which is delivered to the solenoid valves and pneumatic control valve to achieve ventilation and breathe action, and finally the gas reaches the cylinder . The cylinder can complete the valve body on and off, so as to realize the pneumatic system of the automatic control.

Engineering Design Education

This paper discusses the role of the laboratory in engineering design education, and specifically, how laboratories can be used to help meet elements of the CEAB requirements for engineering design and in doing so, complement the objectives of design project courses. Examples are taken from two courses offered at Queen’s University: 1) automatic control systems and 2) mechatronics engineering.
