    I need a simple literature review of purely-analog electronic implementation of fractional-order elements. I just need you to identify the papers available in literature, and indicate a summary about the paper you&quot;ve found. Of course, you need to indicate what papers are already available.No need to format the paper properly as a technical report since it will only be for my personal use. I just basically need to know what is out there?The output of your work will just be an MS Word file. If you can work on this research, please bid.

    A Reaction Wheel Pendulum is a standard topic in most physics courses because it includes some physical subjects such as the simple harmonic motion, the period of oscillation, the acceleration of gravity, the center of mass, the moment of the inertia and momentum. The reaction wheel pendulum adopted in this project has a motorized propeller at the center of wheel so it can lift the pendulum after given voltage. This concept of pendulum system is useful and can be applied in real life. The reaction wheel pendulum system has many applications such as measurement, scholar tuning, coupled pendulum and entertainment.The control problem in driven pendulum system is controlling the pendulum behavior, such as the stability, rise time and overshoots with adjusting the given voltage.LQR controller is Linear-quadratic (LQ) state- feedback regulator for state-space system, appropriate matrix Q and R to enable system to achieve optimal stability by modifying weights in the matrix Q and R corresponding variables. The purpose of this project is to design LQR for stabilizing a reaction wheel pendulum. The pendulum with this controller reaches a steady-state angle with desired transient response.

    I need a project with two spreadsheets: one to describe the pendulum movement and all the physics that implies, and another spreadsheet of &quot;half&quot; a pendulum (a water-wheel, for example). No macros allowed.The real objective is to determine the Force difference when the velocity is increased at all the angles.What I want: an Excel spreadsheet of a non-frictionless pendulum movement, it&quot;s oscillation, restoring force, amplitude, period, centripetal force, potential energy, kinetic energy, velocity, etc, regarding it&quot;s mass and, of course, it&quot;s length. On top of this, the change in pendulum&quot;s velocity if an external force is applied (and, of course again, it&quot;s period), during a specific arc. For example: suppose that top is 0 degrees and bottom is 180; Let&quot;s say that I apply a specific acceleration (or force) when the pendulum is at 90 degrees and I keep this force applied until it reaches 120; then I stop. What would be the bob&quot;s velocity change? What would be the centripetal force after this external force? ( I was thinking of a simple spreadsheet, where these external values would be incremented manually on each cell, with the values being added. If no external value, then 0 would be added). The objective of this is to determine the external force needed to maintain the pendulum in a complete 360 turn; it&quot;s centripetal force at various angles; it&quot;s velocity.So it&quot;s going to be a spreadsheet based on the angles (0-360, in ten degrees increment) and the resulting force at these different angles. The other spreadsheet would be a multiple pendulum, where the weight is placed on top (180 degress) and dropped at the bottom, just like a water wheel. In this spreadsheet, we can vary the number of buckets, but I would ask for the analysis of just 6 buckets and another of 8 buckets (when half of them are filled, of course). This analysis will have to consider the amount of time spent from top to bottom, so we can do a simple integration to get the energy.The analysis should contain a variable counteracting force (like a pulley, a generator or something), and what would be the wheel&quot;s angular velocity based on it&quot;s length, and the resulting kinetic energy and torque at the shaft, the counteracting force and the top-bottom time. ***MILESTONE RELEASE POLICYWhat I need is the project to be done. Completely. Fully. Working. In all it&quot;s extent. Period. I don&quot;t want half of a project, or a partial schematic, or partial code, or partial something whatever. What I want is the FULL complete project and this is what I am willing to get and, of course, pay for.Accepting a project signifies a freelancer&quot;s agreement and obligation to deliver services that match the employer&quot;s project specifications. This includes abiding by the delivery deadline and delivering the required output in full. Milestone payments are intended to be released upon verification that all requirements relevant to the milestone payment were met. Partial output does not signify partial payment unless agreed upon by both parties beforehand.By this, I am creating one full milestone only, to be released when all that I asked for up here is delivered. This is why I tried to be so criterious about each part. No exceptions will be made. *****PLEASE BID ONLY IF YOU ACCEPT THESE TERMS.
