This study proposes the design of two efficient nature inspired intelligent optimal controllers, flower pollination algorithm (FPA) and bat algorithm (BA) for obtaining optimal path using an autonomous mobile robot in an unknown environment. FPA is based on the pollination process of flowering plants, which transfer pollens by using different pollinators. On the contrary, BA depends on echolocation...
Intelligent mirrors, which continue the works today and will take its place in the future technology, provide both mirror and computer aided information services to its users. Thanks to the microcontroller cards onboard, these systems, which can connect to the internet and take data from the internet, can show this information on the places located on the mirror. In the scope of the study, the developed...
This paper shows the relationship between switching/sampling frequency, samples number and sine wave fundamental frequency with the intention of giving a basis to understand how the algorithm was designed. It also punctuates mathematical and implementation constraints considered in the optimization algorithm design. Similarly it explains the numerical methods and procedures used in the algorithm to...
This paper presents the design of a digital controller for a 600 W Boundary-Conduction-Mode (BCM) interleaved boost converter used in an ac-dc Power-Factor-Correction (PFC) power supply. The output voltage of a typical boost PFC rectifier contains a 2nd harmonic ripple. Therefore to achieve good power factor, the output voltage compensator must have a low bandwidth, in order to sufficiently attenuate...
This paper further develops the concept of very large size flash-memory-based pulse-width-modulation (PWM) with the implementation of an over-modulation algorithm for a three-phase inverter. The compensation of voltage for linearization is incorporated within the same flash memory with a multi-optimal PWM generator. Using flash memory demonstrates a low cost alternative to advanced processors. This...

This paper focuses on the design and implementation of a digital closed-loop control scheme to maintain the 180° phase shift of an interleaved Boundary-Conduction-Mode (BCM) boost converter. The closed-loop control scheme operates by differentially modulating the on-time of each phase to adjust the phase-shift. Zero-Current-Detection (ZCD) circuits control the turn-on instant for the MOSFET of each...
In order to develop the bottom driver software more rapidly and efficiently which are used in automotive battery management system and to get rid of high dependence on the hardware and low reusability of the drivers in automobile controller, this paper puts forward a kind of driver design method based on automotive open system architecture (AUTOSAR). Simulation modeling module has been made with the...
Real-time DataBase Management Systems (RTDBMS) have been considered as a promising means to manage data for data-centric automotive systems. During the design of an RTDBMS, one must carefully trade off data consistency and timeliness, in order to achieve an acceptable level of both properties. Previously, we have proposed a design process called DAGGERS to facilitate a systematic customization of...
For the proper and stable operation of a microgrid, an accurate estimation of the key parameters under various disturbances is the most important task for the rest of the control blocks. In this paper, a SOGI-FLL scheme aimed for voltage and current parameters estimation in single-phase power system is implemented using high speed ARM microcontroller. The main contribution in this work is the ability...
This paper presents tools the author uses to enhance student motivation in a microcontroller-based embedded systems course. The course is offered as part of a requirement in a computer engineering degree program. In the traditional lecture-based teaching and learning process, information typically flows in one direction with very little active involvement by the students. There are a number of techniques...
This paper describes a sophomore-level ECE course that bridges the gap between the maker movement and typical engineering design courses. This course incorporates the practical skills of fabrication, assembly, and hardware integration found in makerspaces but deepens the perspective from one of getting it to work to designing it to work well and efficiently. This paper discusses mastery-based education...
With the increase in population and automobiles, the traffic jam in urban areas is becoming a critical issue. These traffic jams especially at the intersections not only increase the delay for drivers, but also increase fuel consumption and the air pollution. The fixed-time traffic light controller is one of critical factors that affect the traffic flow at intersections. This paper proposes a new...
In this paper, we present a method of learning desired behaviour of the specific robotic system and transfer of the existing knowledge in the event of partial system failure. Six-legged robot (hexapod) built on top of the Bioloid platform is used for the method verification. We use genetic algorithms to optimize the hexapod's gait, after which we simulate physical damage caused to the robot. The goal...

Common hospital monitoring set up includes nurses taking rounds throughout their assigned wards and checking the patient's vital signs. This process is very time consuming and prone to human errors, especially for large scale hospitals. As a solution, an Internet of Things (IoT) based pulmonary monitoring system was proposed. The system uses a single-lead heart rate sensor connected to a microcontroller...
The majority of modem devices become smart and programmable. It simplifies their use, but complicates development. A variety of areas of the electric drive application and constant improvement of it's elements create problems in education of this specialty. On the example of Department of Electric Drives of Moscow Power Engineering Institute ways of their decision are discussed.
Advances in the information and communication technologies have led to the emergence of Internet of Thing (IoT). IoT allows many physical devices to capture transmit data, through the internet, providing more data interoperability methods. Nowadays IoT plays an important role not only in communication, but also in monitoring, recording, storage and display. Hence the latest trend in Healthcare communication...
This paper presents the application of a multiple switching pattern selective harmonic elimination on three level inverter. The aim of this work is to eliminate low rank harmonics (3rd, 5th, 7th and 9th) from an AC voltage waveform generated by DC to AC converter and also control the fundamental component, the modulation algorithm is based on the Newton-Raphson method which is one of the simplest...
