A fuzzy logic control law and a digital pulse width modulation (DPWM) technique are used as a computational solution, while the implementation is carried on a reconfigurable computing hardware platform. The computationally intensive tasks are implemented as custom hardware accelerators using VHDL, while data flow and data control are implemented in software using the system-on-programmable-chip (SoPC) approach. Computer simulation results show the effectiveness and merit of this design flow. In addition, the real-time applicability of this heterogeneous controller is exemplified on an armature-controlled DC motor platform.

Phase of the functional and technical study of which reflects on the aircraft maintenance component, without forgetting the phase of synthesis of the landing system mechanisms. The approach presented relates to the description of the different instruments and languages used for the control of vibratory behavior in a maintenance plan. Active devices are used mainly in systems where the excitation acts permanently on the system and the minimization of the amplitude of the vibrations is the dominant criterion. This is the reason why it is important to plan and control the technical aspect which will contain the landing system from the point of view of geometry, torques, positions, speeds and accelerations, and trajectories from the mechanism design phase.

Hence, sophisticated software and hardware were introduced to the power grid, which makes it a smart grid. This chapter is an introduction on smart-grid technology; thus, microgrids are explained, and the use of multiagent system in centralized/decentralized energy management systems are discussed and compared. Smart agents are an emerging technology for decentralized computation and data storage. Hence, in this chapter, decentralized energy management system is created basing on multi-agent system technique where sources and loads are considered as separated agents each of them. After that, these sources and load create a microgrid and each microgrid can be considered as an agent. The work proposes an approach for load supplying optimization to decrease the microgrid cost and enhance its efficiency.

It can do almost all tasks that either the human can do or not as well as the dangerous tasks. The researchers recently develop robots, which can see, smell, smile, speak, touch, walk and talk using the more advanced technological tools such as computer aided design. However, these humanoid robots cannot react as human, so what is missing?, what is about the spirit? Does robot have the spirit? This paper answers these questions and presents imperfection of humanoid robot.

The first part of this paper deals with the presentation of the background of quadrotor modeling; the second part describes the direct control of the drone using the backstepping control principal. This principal is based on the division of the system into several sub-systems in a cascade, which makes the control laws generated on each subsystem, in a decreasing manner, until a global control law for the whole system is generated. The simulation results for the sm controller are generated on the MATLAB/Simulink platform; the results show a good performance in both the transient and steady-state operations.

Thus, advanced autonomous mobile systems are primarily required for an off-road robot to sense and understand its environment, while ensuring, at the same time, robustness under compromised conditions. Therefore, this book addresses the problem of the design, implementation and realization of an autonomous mobile robot navigating in an uneven environment. Our proposed study would be useful for real-world robotic applications such as intelligent navigation for motorized wheelchairs, surveillance and security purposes, in Nuclear power plants where humans are prone to harmful radiations, for planetary exploration and every where the robot is expected to encounter rough terrain.

First, Motion sensors detect movement indoors and outdoors to guard against intruders, protect valuables and more. Thus, if any movement, RFID reader will be activated and database will be scanned to identify the persons who have the access to the home. This enhances the effectiveness of the security system and provides the user with the complete, wholehouse protection he needs. An RFID badge can be used to unlock the door and access to the home. Alerts also are received on the smart phone if motion is sensed in a protected area inside or outside; giving the user the information it needs to act quickly. The door can also be remotely locked/unlocked. A microcontroller (ATmega2560) is used to control the entire system, and GSM is used to send alerts to the Smartphone. An Ethernet shield that connects the microcontroller to the database (DB) is also added.

In this work, new approach built upon the internet of things (IoT) has been proposed; microprocessor based devices are used on path generation and robot platforms focus on path following. Hence, two different algorithms, Bug0 and Potential Field, are merged to create a hybrid approach using fixed cell decomposition for the environment and a map of this environment is created. Data are exchanged via the wireless LAN (local area network). The obtained results surpass the traditional implementations where robots were making every decision. Moreover, the proposed topology accomplishes scalability easily. Therefore, this work consists of the development and the implementation of intellectual and robust software to automate the robot tasks. A map, built basing on data acquired from a camera, will activate the whole process; then, a computer (or any microprocessor device) will treat these data and generate an optimal trajectory and send it to the robot platform via the wireless medium to enable it to navigate from any given initial point to any target. The robot is also able to detect a change in the environment and report it to the computer to get a new path.
