4.1.4 Development of Feed Forward Control model in Simulink To implement feed forward control. Firstly, the transfer function of the linear DC Motor model has to be obtained. Actually in our case, the input of the plant is current so the transfer function of the mathematical model in ratio of angular velocity to current has to be obtained. It is given by: G(s)=Ω_1/I_a =R_A/K_M 1/(T_e s+1) where T_e=(J_meq R_A)/(K_m Cϕ) is electro-mechanical time constant. The feed forward control could be…

I selected the military becauses the military runs in my family and i enjoy learning about it as well. I never thought about doing a senior project. My first choice was actual to be a robotics engineer which my job would be to build and design robots. My personal growth helped me choose the military because my mental and physical abilities.Looking forward in my life choosing the military will help me with my mental and physical strength and my discipline. I hope to learn more about the history…

Motor & Gearbox The mirrors are required to rotate specific angles. To be able to achieve specific angles we need a stepper motor. The stepper motor is known to divide one revolution into equal steps which is our main requirements for the rotation of the mirrors. Figure ‎2-13: The Stepper Motor The following table shows the stepper motor specifications: Table ‎2-1: Stepper Motor Specifications Current 4.2 A Angle 1.8° Torque 8.34 N.m The desired torque calculated to withstand the mirror…

How Electro-mechanical Actuator Works? A Rotary Electromechanical Actuation system with an Electric Motor, a gear box & an elastic spring to absorb peak torque loads experienced during operational life. The Schematic below describes the system. Fig. 1.1 Rotary Electro-mechanical Actuator Gearbox Requirements: The Gear Box at the Motor Output is intended to amplify the torque output of the Motor with reduction in speed. The tentative ratio is set at 10:1. Functional Requirements of…

Ever since I was young I have recognized my intrinsic passion for leadership, service, and computers. Although I was never known to turn down a game of capture the flag or flashlight tag, I spent a lot of my time reading about the Navy SEALs or about how to distinguish an F-15 Eagle from an F-14 Tomcat. I would stay up late to figure out how to make programs or build websites for fun. One of the more vivid memories I have is when I decided to disassemble my family’s new x486 computer, only to…

Have you ever heard of Samuel Morse? If you have then you know that he was a co-inventor of Morse Code. Morse Code is a systematic way of transmitting information via code and it is sent either from light or from off and on tones. Samuel Morse is known for much more than Morse Code, however. He originally gained his reputation for being a portrait painter and by helping invent the single-wired telegraph. Because of what is being called the Industrial Revolution many new inventions like Morse Code…

Technological innovations had a major impact on the U.S during the Gilded Age. Our major inventors were Thomas Edison and Nicola Tesla. Thomas Edison invented the DC light bulb however, Nicola Tesla invented the AC light bulb. Tesla worked under Edison as his apprentice when he was working on the light bulb. While Tesla was under Edison, JP Morgan was trying to find an industry that he could rise from the ground, and that's when he found Edison with electricity and the light bulb. JP…

The motto of the University of Chicago, in English, means “Let knowledge grow from more to more; and so be human life enriched,” and to me, the idea behind that message makes up a great deal of the allure of the University of Chicago. Expanding my knowledge and further enriching my life are two of my greatest goals, and the University of Chicago embodies those ideals like no other university can. Through the variety of excellent, easily accessible opportunities in the city of Chicago and the top…

The world as we know it, started to develop when the prehistoric humans discovered tools to supplement their needs and use it as an accessory to augment themselves to diversify the potential of their existence.**About 2.5 million years ago, the technology began to shape the mankind when humans used stone tools to hunt, start fires and bury their dead. Throughout the evolution from the stone age till today, humans have been immensely dependent upon technology to shape their world and provide…
