  • $214 USD In Progress

    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.

    Reaction wheel pendulum or known inertia wheel pendulum as is similar to inverted pendulum but this reaction wheel pendulum using a dc motor which is attached to its reaction wheel or disk.In this project there are two main things which need to control there are - swing up control and stabilization control when the pendulum is at an upright position by using Linear Quadratic Regulator (LQR).This is the example video of Reaction Wheel Pendulum...

  • $289 USD Yesterday This is a link to a virtual catapult that I&quot;d like to emulate on my Joomla 3 website. It doesn&quot;t have to look exactly like this, in fact it shouldn&quot;t to avoid trouble, but it needs to have similar functions plus one more, the mass of the projectile. Note that it must emulate the laws of earth physics and behave like a real catapult. Also each setting needs to have some natural randomness to it. Normal distribution randomness is best. I need a way to tune how much randomness is in it with settings the code or in an interface that only I can see but code changes are OK as long as it&quot;s not compiled. I&quot;ll install it on a page on my website. You&quot;ll write the code, annotate it with at least one comment per 10 lines of code or every time a new function is created, and give me the source code and directions how to install it on my site. Project will be finished when I can operate it successfully and reverse engineer how it works with a regression equation.I did a similar project here about 8 years ago in java which no longer works well. I posted a different project to convert it to javascript or html5 but don&quot;t like the vague responses I got and suspect that people don&quot;t like modifying other people&quot;s code so want to just start from scratch. Many of the quotes to convert the old one were more that it cost to make it in the first place. My old simulation had several problems so I think it&quot;s better to start from scratch and I like the Sigma Zone one. I&quot;d be happy to simply use theirs forever but since I don&quot;t own it, it can disappear any day and I want guaranteed access to something that behaves like this. Feel free to ask questions!
