A man-machine interaction experiment in the real-time continuous control sense is presented. The computer program is given and described, together with some representative results with regard to plant order, display effects and training effects. In particular, the importance of the selection of the displayed variable is emphasized. The experiment has been helpful in the appreciation of the effects of display gain selection and the inclusion of the derivative terms in the displayed variable, as well as demonstrating the importances of plant order and operator training, by allowing time response shape and criterion value comparisons. The nature of the conclusions reached can be generalized to automatic control, helping students of control systems.

carried out with specified periodic actions, we can distinguish their multiplicity, diversity and originality. However, with regard to the sterilization processes in autoclaves, there is currently no high-quality control system for them, which still determines the relevance of this task. The article offers a selection of criteria that can be applied to the automatic control system, taking into account the specifics of the processes that occur during the sterilization of canned food using an autoclave. This article also discusses the structure of this process using the basics of the theory of automatic control. In addition, it provides a simulation of these processes. In contrast to the existing structures, the proposed automatic control structure is characterized by openness, which increases the design efficiency in the development of such control systems. The basis of this approach in the form of a two-circuit four-channel controller, allows you to improve existing and create new automatic control systems for sterilization plants.

Introduction. The exponential growth of measurement information caused by ongoing complication of technical and production facilities necessitates the development of improved or brand new information and measurement systems, including those performing adaptive automatic control functions. Automatic criteria-based selection and reduction of measurement information continuously supplied by multi-parameter sources characterizing the objects under study require algorithms ensuring reconfiguration of automatic control systems during operation. In comparison with automatic control systems based on time-division channelling, the considered adaptive systems provide timely information on the pre-emergency and emergency operation of a facility.Aim. To develop an algorithmic support for adaptive automatic control systems using asynchronous-cyclic and parallel-sequential operating algorithms, as well as to compare the proposed algorithms in terms of their, control reliability, compression ratio, operation speed and the error associated with multi-channelling.Materials and methods. The algorithms proposed for supporting the operation of adaptive systems were developed on the basis of queuing theory and simulation modelling using the MatLab/Simulink programming languages, C++.Results. The developed algorithmic support for automatic control systems based on asynchronous-cyclic analysis of deviations allows the amount of redundant information to be reduced by more than 4 times and the operation speed to be increased by 1.5 times. The developed algorithmic support for automatic control systems based on parallel-sequential analysis of deviations allows the error associated with multi-channelling to be reduced by 1.4 times, thereby bringing the control reliability of such systems closer to that of continuous-control systems. An analysis of the graphs of the error associated with multi-channelling showed that the automatic control systems based on parallel-sequential operational algorithms are invariant to the law of distribution of input quantities, compared to the systems based on asynchronous-cyclic operational algorithms.Conclusions. The proposed algorithmic support can significantly decrease the redundancy of information and improve the metrological characteristics of automatic control systems. The use of the developed algorithms in automatic control systems based on time-division channelling render their control reliability comparable with that of continuous-control systems.

Wide Range

“Cyber crime” has been used to describe a wide range of offences, including offences against computer data and systems (such as “Hacking”), computer related forgery and fraud (such as “phishing”), content offences (such as disseminating child pornography), and copyright offences (such as the dissemination of pirated content). The word “Cyber Crime” has been derived from the words “Cybernetic” which means the science of communication and automatic control systems in both machines and living things.
