Dynamic Behavior of Brushless DC Motor under the Application of PI, PD, PID, and Fuzzy Logic Controllers

ABSTRACTThe importance of Brushless Direct Current(BLDC) motors in modern day technology cannot be overemphasized. Its improved performance in terms of efficiency, reliability, noise and dynamic response, better speed versus torque characteristics, higher speed range, and durability over the Brushed Direct Current motors could not be wished away.This work investigates the performance of a BLDCmotor with the application of PI controller, PD controller, PID co...

Design and costruction of bicycle ergometer

CHAPTER ONEINTRODUCTION1.1 BACKGROUND OF THE STUDY: trolling body weight, reducing the chances of heart diseases, reducing the risk of diabetes and some other chronic diseases by improving the functions of the heart, lungs and improving the biomechanical system of the body. Aside surgeryand medication, several methods have been proposed for the prevention and treatment of heart conditions. One of such methods is the use of regulated and supervised exercise as therapy both for prevention of he...

Design and Construction of a Model Power Generating Windmill

This project covers the design and construction of a power generating windmill. The designs was carried out based on long-term available wind data of bida at 10m above the ground level. The average wind speed for Bida is 5.24m/s and rated turbine wind speed is 6.29m/s. The design of each components of the system were carefully constructed in a well equipped workshop within the school premises. Calculations were done manually for each components of the system and the results was match with the...

Statistical model to predict dry sliding wear behaviour of Aluminium-Jute bast ash particulate composite produced by stir-casting

A model to predict the dry sliding wear behaviour of Aluminium-Jute bast ashparticulate composites produced by double stir-casting method was developed in termsof weight fraction of jute bast ash (JBA). Experiments were designed on the basis ofthe Design of Experiments (DOE) technique. A 2k factorial, where k is the number ofvariables, with central composite second-order rotatable design was used to improvethe reliability of results and to reduce the size of experimentation without loss ofacc...

Design of Next Generation Civil and Military Aircraft with Ultra-High Bypass Engine using Composites, Advanced Materials and Technology

AbstractIndirect combustion noise had not been attracting research in the past, but recent indication seems to prove that it could be a threat in the future if not addressed. Means of reducing this type of noise to a low decibel value was also included. Noise is due to the ingestion of distorted atmospheric turbulence, as the two set of blades rotate in different direction. Open rotor noise is higher since the rotors are fully exposed to oncoming turbulence and lack ducting or a nacelle to at...

Design of Effective Solid Waste Management System: A Case Study of Ifite-Awka zone, Anambra State

Focuses on the maximum volume of waste generated in a particular month in a particular area and uses a heuristic model for it's analysis.Research ProblemA proper, efficient, reliable and hygienic waste handling and disposal technique tells more of our maintenance culture but the capacity and ability to efficiently manage the  waste  becomes inadequate.   The need   for this   study a rose because effective waste management is a tool for sustainable deve...

Performance Assessment of the Firefighting Personal Protective Tunic

ABSTRACTThis project centers on addressing the issue of the lack of research and development in Nigeria, in this case, looking into the firefighting and emergency sector. In this industry, the safety of the firefighters is of paramount importance as it is only then that they can fully carry out their duties and tasks. Of all the products that make up a complete assemble of the firefighters’ PPE, it is their personal protective tunic that was used for this project as it is the basic and most...

Design and Construction of a GSM-Controlled Pick and Place Robot

ABSTRACTThe modern manufacturing environment is dynamic and uncertain. In line with the globaltrend in manufacturing, this project is carried out to explore into the potentials of robots inmanufacturing, service industry, and domestic use. The robot was designed and constructed to incorporate the use of mobile phones as control mechanism via dual-tonemultiple frequency (DTMF). Various components such as the Gripper, Gears, Chains, and Control system were designed with good factor of safety...

THE DEVELOPMENT OF A LARGE-SCALE MULTIPURPOSE HOT MEAL PROCESSING EQUIPMENT

The development of a large scale multipurpose hot meal processing equipment was designed andsimulated for market oriented production as reported in this paper. This project involves thedesign,   design   layout and   performance   of   the  Hot  Meal   Processing   Equipment.   It  has   one compartment; the Agitator compartment. The Agitator has three curves like paddles arranged symmetri...

Development of Laboratory Hot Compression Mounting Press Machine

Abstract.This research focuses on the design, fabrication and performance evaluation of a laboratory hot mounting press machine for metallography using locally sourced materials and indigenous technology. To achieve this research objective, working drawings were produced which were used to produce the parts of the machine. Mild steel plates were used for the housing and the movable platen while stainless steel and mild steel rods were used for the production of the mold and the sturd res...

DESIGN AND CONSTRUCTION OF ICU/REHABILITATION ADJUSTABLE BED USING LOCALLY SOURCED MATERIALS

The focus of this project was the development of an ICU/Rehabilitation adjustable bed for the hospital and home environment. The project was initiated with the desire to develop an innovative, effective and inexpensive mechanism that would require an electrical supply. The design was performed systematically using various methods, procedures, techniques and materials to aid the process. One of the method used is carpentry, which was used to make the bed framework and the adjustable floo...

DESIGN & CONSTRUCTION OF HAMMER MILL MACHINE

Processing involves conversion of raw materials into varied forms of finished products. It is carried out in different fields of science and engineering. Agro and Agro allied industry, food manufacturing, pharmaceutical, ceramic, civil engineering industries etc are involved in processing. The breakdown of large stones to an acceptable size for road construction is the business of the quarry industry (civil engineering). The grinding (milling) of clay materials for the purpose of production o...

BASIC LUBRICATION PRINCIPLE

This write-up gives an overview of lubrication, lubricants, their types and general properties, and the principles of lubricant application. It further emphasizes on the different methods of lubricant application, specification, selection and storage.

DESIGN OF 2TONNES AUTOMATED HYDRAULIC JACK

ABSTRACTThe design of 2 tones automated hydraulic jack was carried out using the basic principles of machine design and analysis. The hydraulic jack was designed with a 204watts wiper motor with the output lever having a torque of 30Nm.  The effective diameters of ram and plunger pistons were found to be 12mm and 6mm respectively, when the load lifted was 2000N with mechanical advantage being 3.4. The working stress was 21MPa when the effort applied at the handle by the lever w...

SUSTAINABLE E-LEARNING FOR NIGERIAN EDUCATIONAL DEVELOPMENT

ABSTRACTAs Nigeria aims at optimizing the implementation of the E-learning programme in tertiary institutions, this paper discusses the ways by which the implemented E-learning can be sustained. The discussion was carried out using data derived from students, teaching staff and telecommunication engineers in Nigeria using Owerri metropolis as a case study. Data analysis was carried out and analyzed using excel and Minitab. Conclusions and recommendations were drawn for effective imp...
