Life support devices developed for use in the treatment of respiratory insufficiency are called mechanical ventilators. Mechanical ventilators that mimic gas exchange between the respiratory system organs and the atmosphere using different methods are critical medical care devices that allow the patient to maintain respiratory functions. In this study, a mechanical ventilator prototype was developed for use in transferring intensive care infants between medical institutions. The ventilator prototype is designed to be used as a CPAP (Continuous Positive Airway Pressure) device for neonatal resuscitation if desired. Prototyping work has been carried out taking into account the safety precautions and sensitivity parameters specified in the relevant standards of the neonatal ventilators. The ventilator can be able to operate with pressure and volume control.

In this paper, an H∞ controller is designed for disturbance attenuation of magnetically levitated steel plate. The system contains U-type hybrid electromagnet which constructed by using permanent magnet. A detailed model having nonlinear attraction force of a U-shaped hybrid electromagnet is presented and linearized for controller design purpose. Based on the linearized model, the H∞ controller is designed to minimize air gap variation under unknown loading disturbances. Thereafter, a set of experiments conducted to compare performance of the H∞ controller with our previously published I-PD controller on the same experimental setup.

Predicting accurate efforts at the early stages of the Software Life Cycle is one of the greatest challenges in software industry. Effort estimation remains a very difficult task since the software requirements are not well known and understood/or the details have not yet been specified. Thus, most of software effort estimation models are built on using historical project data. For this purpose, CBR based prediction models have been extensively used. In CBR techniques, choosing the most similar case has a strong impact on the prediction accuracy, nevertheless, it remains a hard task especially on the presence of alternatives projects; projects that are equally similar. This paper proposed a new method to select the most appropriate case by using ant colony optimization algorithm. The ACO algorithm will be used to search for the best case of past cases based on the different features similarity values (FR_similarity, NFRs_similarity and DPs_similarity). To verify the efficiency and performance of the proposed model, an example was conducted and the results were compared with that of the real estimation. The results of the example show that proposed model in this paper is an attractive alternative to retrieve the most appropriate case and is useful and beneficial for decision making during the effort estimation.

The paper presents a novel method of PID controller tuning dedicated to regulatory control of second order plants. To this end, a case study of level control is performed for a system of two non-interacting tanks. Disturbance attenuation is analyzed analytically and interpreted using root loci. Closed-form expressions to calculate dynamical parameters of control signal and control error are derived and the influence of measurement noise on control signal is studied. Immunity to the change of working point is treated as one of major factors for performance assessment. Superiority of the presented approach over other contemporary design methods is highlited. The performance limit is shown to depend on measurement noise characteristics.

In this paper, a robust guaranteed cost observer-based state feedback controller design problem is studied for a class of linear uncertain systems with norm-bounded uncertainties. Employing the Lyapunov stability theorem, the criteria of robust stabilization are investigated within the framework of linear matrix inequalities (LMI). The feasibility problem of the stabilization criteria is solved using the technique of cone complementary minimization algorithm. Moreover, the minimization of the guaranteed cost is also obtained. Finally, two numeric examples are presented to illustrate the proposed stabilization which provides a considerable improvement.

One of the situations where significant problems may arise in two-input two-output (TITO) systems is the existence of interactions with cross-couple of inputs and outputs. This situation may be challenging especially for the system analysis in process control. As long as the condition that the system should be decoupled is met, control problems to be investigated for this kind of systems become meaningful. This study deals with the design of non-interacting dynamic diagonal controllers for two-input two-output systems. Here, it is aimed to obtain the needed filter for decoupling and then to design the controller to satisfy the necessary specifications. The decoupling filter and controller design procedure for disturbance attenuation and reference tracking is defined via general control configuration. Here, the main objective of the study is to keep the system decoupled where an optimal controller is designed to increase the reference tracking and disturbance attenuation performance of the overall closed loop system. The efficiency and success of the proposed method is illustrated via simulation studies.

This paper presents two backstepping control design for Unmanned Aerial Vehicle (UAV) attitude tracking subject to uncertainties and external disturbances. We first propose an extension to attitude tracking control design using quaternion based backstepping procedure from attitude stabilization. Next, we develop an original integral backstepping control law for UAV attitude tracking. The proposed control includes an integral term that improves tracking performances and provides better disturbance rejection. The obtained control law contains a proportional, a derivative and an integral terms so that it is a PID like nonlinear controller. Both quaternion based controllers allow passing through singularities usually caused by Euler angles representation. Global asymptotic stability of the closed loop system is proved for both controllers via systematic constructive Lyapunov functions. Simulations results with Matlab-Simulink for stabilization, tracking, robustness tests and singularities avoidance are given for each controller. Finally, experimental results are validated in real-time on the Quanser 3 degree of freedom (DOF) Hover test bench and show the efficiency of the integral backstepping controller and the quaternion superior performances.

Network management processes of Wireless Body Area Networks (WBANs) such as installation and configuration are quite complex because of heterogeneous structure and limited resources of WBANs. In addition, the lack of a manageable and flexible structure poses an important problem in WBANs. The software-defined network (SDN) approach suggests a new network architecture that is simple, flexible, and manageable and has less workload. This approach is considered to be a solution to the above-mentioned problems of the WBAN architecture. In this context, WBAN architecture based on SDN approach, a new network approach for WBANs, is proposed in this paper.A controller as SDN control unit is responsible for all network-related management and control operations in WBANs. This unit effectively and efficiently manages all the wireless communication processes necessary for the coordinator nodes to communicate with each other and with the controller. The throughput and end-to-end delay results of the proposed architecture are examined for the performance analysis. The results show that the proposed network architecture improves the performance of the traditional WBANs structure and simplifies the control and management processes.

The energy consumption in the dwellings continues with a steady increase which contributes to the overall consumption. Population growth, increasing comfort levels and daily usage of the electrical appliances are driving the domestic electricity demand to higher levels. For this reason, it is very crucial to aim domestic consumption in order to reduce the global consumption. This required changing and understanding consumers’ awareness, behavior, and increasing their knowledge in the subject of energy use. Providing that households are conscious about electricity consumption and studying factors affecting them can help to reduce energy consumption in residential areas. For this reason, a graphical user interface was created in this study in order to raise awareness of energy to consumers and thus reduce energy consumption. This study presents a graphical application for monitoring household consumption based on catalog data of various household devices to promote energy consumption awareness in the users of this application.
