Task 4 A Power Amplifier control system is shown in figure 1. 1. Find the values of K and Kr so that the closed-loop system will have a Mp = 50% overshoot and the minor loop will have a damping ratio of (=0.5169. 2. Provide a step response and a frequency response graphs. 3. Using K from step (a), compare the expected performance of the system without tachometer compensation to the expected performance with tachometer compensation. 4. Using the values of K and Kr as previously determined, design a lead-lag compensator cascaded to the forward path to improve transient time performance by at least three folds, and a minimal steady-state error when the input is a step input. Show MATLAB script and step response graph before and after the use the compensator. Power Amplifier and Amplifier Plant R(s).

I need answers to questions 1, 2, and 3 pertaining to the print provided. Note: A tutor keeps putting 1 question into 3 parts and wasted so many of my questions. Never had a issue before until now, please allow a different tutor to answer because I was told I am allowed 3 of these questions.
Keep the same colors the same graph, basically keep everything the same just make the line with a small curve just as shown on the picture Keep everything the same just make the line less curvy please do not change the colors of the line and the circles do not change anything besides the curve of the line. Use this code on MATLAB and fix it. % Sample data for Diesel and Petrol cars carPosition = linspace(1, 60, 50); % Assumed positions of cars % Use the 'seed' function instead of 'rng' seed = 50; % Define your seed here rand('seed',seed); % Assumed CO2 emissions for Diesel and Petrol CO2Diesel = 25 + 5*cos(carPosition/60*2*pi) + randn(1, 50)*5; % Random data for Diesel CO2Petrol = 20 + 5*sin(carPosition/60*2*pi) + randn(1, 50)*5; % Random data for Petrol % Fit polynomial curves with a reduced degree of 2 pDiesel = polyfit(carPosition, CO2Diesel, 2); pPetrol = polyfit(carPosition, CO2Petrol, 2); % Generate points for best fit lines fitDiesel = polyval(pDiesel, carPosition);…
THIS IS NOT A COMPLETE QUESTION, IT JUST NEEDS TO HAVE THE STEPS IN THIS WAY. (PLEASE DON'T SEND ME A CHEGG ANSWER! I HAVE A CHEGG ACCOUNT. I SENT THIS QUESTION CHEGG AND I DON'T WANNA TAKE SAME ANSWER LIKE THAT! PLEASE JUST SOLVE ON YOURSELF OR LEAVE PLEASE. Fluid Mechanics question.)
HELLO, CAN U HELP ME TO MY RESEARCH PART?, MY RESEARCH PART IS DATA GATHERING PROCEDURE, AND I'LL SEND THE SAMPLE THAT MY TEACHER GAVE ME, THIS IS MY TITLE BTW " Students who play Axie Infinity as scholars do not make enough money to support their studies: a qualitative study of Axie Infinity scholars among the students of Precious High Academy" THANKS!
6. Please help me solve this mech. engineering question
Last person got every single question wrong and didn't include units. Please help.
The class I'm taking is physics for scientists and engineers! **** I need help with part D only***** Can you please write out the solution and not type out the solution? I had to reask this question because the last tutor typed out the solution and it was very hard for me to follow . Please and thank you for the special request. I have attached the problem. Please view attachment before answering. Thank you!
A.) Sketch:[Draw a sketch that represents the situation of the problem, while showing all the variables included in it (vectors or scalars as forces, , displacement, position, etc.).] B.) Approach:[Mention all the laws, principles or concepts, as well as the mathematical equations that solve this problem. Step by step.] C.)Solution:[Develop the physical or mathematical equations used for the solution of the problem and highlight the partial and final answers. Be clear and organized.]
Please draw the right side view. Don't copy from anywhere else. Please write the dimensions as well.
I am sorry but your values when plugging in are not the correct values. Not too sure where your values are from but can you please redo the question using the given values in this problem and not from a different problem please? (example, height is not 29, it is 22) all values do not correlate to this problem. I was also told when finding the area of triangle to use (1/2)*b*h*Ad^2 and not 1/36*b*h*Ad^2 Find the moment of inertia and radius of gyration of the section of this bar about an axis parallel to x-axis going through the center of gravity of the bar. The bar is symmetrical about the axis parallel to y-axis and going through the center of gravity of the bar and about the axis parallel to z-axis and going through the center of gravity of the bar. The dimensions of the section are: l=55 mm, h=22 mm The triangle: hT=12 mm, lT=19 mm and the 2 circles: diameter=8 mm, hC=6 mm, dC=8 mm. A is the origin of the referential axis. Provide an organized table and explain all your steps…
Engineering Drawing: DimensionsWhich statements are true? (you can choose more than 1 box) □ The aligned system uses figures and notes that are lettered in the direction of the dimension lines□ Extension lines should touch the object to indicate where the dimension lines are measured from□ It is never acceptable for extension lines to go inside of objects□ Dimension line arrows can be placed outside of the bounding extension lines.□ Center lines are used to indicate axes of symmetrical objects□ Dimension lines are usually constructed with arrowheads as the endpoints and gaps in the middle for the numerical value
