In this study, we propose an odor display device based on the embedded control system, which can realize the reproduction display with different concentration ratio. At the same time, we propose a concept called odor characteristic spectrum (OCS), which is used to describe the odor characteristics of information and display. The odor characteristic spectrum contains four key factors, odor name, odor...
Networked control systems (NCS) have attracted considerable attention in recent years. While the stabilizability and optimal control of NCS for a given communication system has already been studied extensively, the design of the communication system for NCS has recently seen an increase in more thorough investigation. In this paper, we address an optimal scheduling problem for a set of NCS sharing...
The stability of the movement of an Automated Guided Vehicle (AGV) directly affects the safety of the delivered goods. Variation of loads during the delivery process is one of causes of the instability movement of an AGV. This research discusses the design and implementation of the AGV's speed control system to tackle the load and contour variation using Fuzzy Inference System integrated with PID...
Control systems using sensors and wireless networks are becoming more prevalent, due to its ease of deployment: no wires and longer battery life. However, network delays and packet losses can degrade control system performance, which leads us to find the optimal network configuration to minimize that impact. Another main difficulty of having wireless networks for control systems is caused by interference...
We present an approach to dynamically reconfigure the network in the Internet of Things. The approach leverages the new enabling technologies from the Software Defined Networks, and provides a network controller capable to interact with the network switches, to detect faults, and to issue a new network setup. The network setup is defined as the set of communication flows and their associated forwarding...
The rising complexity of embedded control systems and their increasing application to automate safety-critical or mission-critical tasks present a challenge for established development methodologies and tools. Are they able to handle the growing system complexity without compromising either system efficiency or its correctness? This challenge is addressed by the "correctness by construction"...
In 2025 semantic tools for software engineering will be mature, and their frequency of use in software development will still be disappointing.This proposal explains how research directed at building theories of everything (or, at least, important software domains) can consolidate progress and bring semantic tools into the mainstream of software practice.
In this paper, we design an INS/GPS integrated navigation system based on federal Kalman filter for autonomous flight of multi-rotor which contains several parallel subfilter and guarantee the stability of system. At the same time, we present a discrete path generation algorithm for the multi-rotor trajectory tracking. During the autonomous landing stage, on-board computer runs a real-time land-marker...
The design of software architecture is a higher level in the design process of software, which has surpassed the algorithm design and data structure design, and the purpose is to solve some problems in the design and description of the overall system structure. In this paper, the technology and modeling method of software architecture design are studied; the hierarchical structure, execution flow,...
Centrifugal pumps are considered as one of the most common types of pumps in industry today. They are widely-used because their design is simple, they are available in wide range of capacity and head, they have high efficiency and smooth flow rate, and they are easy to operate and maintained. There are many factors that contribute to the efficiency and life time of centrifugal pumps. In this work,...
The Home automation plays an important role in modern lifestyle because of its access in using at different places with high quality which will intern save time by decreasing human work automatically. The home automation is electric devices stand alone and do not communicate; it is programmable, such as sensors remote controller and communication system. Home automation use for electronic control...
The main advantage of conveyor belts that we usually use is that we can avoid material spillage to a considerable extent. This is noticeable when powdered materials like sand, cement, cement concrete, coal, etc. are transferred with their help. Other applications in food processing units, bottling plants, and wood log processing companies also make the study on economization of conveyor belt transfer...
With the advancement in sensing technology, applications are moving from wired to wireless region. The main challenge is the energy consumption of individual sensing nodes. When first node dies system becomes unstable and we cannot make use of the untapped node's energy. There comes the relevance of TSEP like protocols in such heterogeneous network. Heterogeneous in the sense with respect to node...
Solar Energy is most reliable and efficient renewable source for Electrical Power Generation. The electrical power output from the solar panel can effectively be obtained from Solar Photo Voltaic (SPV) Panels. Maximum Power Point Tracking is an algorithm to obtain maximum power from the solar panel effectively. The researchers employed various methods like Perturb & Observe method [1], Incremental...
The more highly automated road vehicles become, the more complex get their control systems along with the taskto identify and reach the safest possible state at an acceptablyhigh probability in as many operational situations as possible.

This paper studies the problem of tracking or disturbance rejection for sampled-data control systems, where the tracking signal can have frequency components higher than the Nyquist frequency. In view of the well-known sampling theorem, one recognizes that any high-frequency components may be detected only as an alias in the low base band, and hence it is impossible to recover or detect such frequency...
