I've written the equation. in fact i,tetha and y are functions of the t! which means i should coup with a equation which is constructed from different derivatives from different functions based on t! please check it up! (4Iθ{dotdot})/β-{(M^2*y{dotdot}^2+...

Hi chiro it is a dynamic model of an electrical system which could be described as below equations. except t,tetha,y and i are constants. f1 - f2 = f3 + f4 f1 = \frac{4 I\ddot{\theta}{\beta} f2 = \dot{\theta} {M^{2}\ddot{y}^{2} + \tilde{M}^2\tilde{g}^2 + 2 M\tilde{M}\tilde{g}\ \ddot{y}}{4...

Hi everyone! I want to design a robust controller for a system which is driven by a PDE. I need to acquire its transfer function in 's' parameter which means it should be transferred by Laplace transformation. I know that the result transfer function will be an infinite series of transfer...

Hi everyone! I am a mobile robot designer in autonomous space robotics. there is a great dilemma in front of me to opt a programming language for the robots between C++ and Java. the most important factor for me is performance of the language when i want to use it for applying very...

thank you very much for your impeccable explanations...!

A high power current amplifier circiut? Hi everyone! My research field is robotics and in one of my designs, i need to amplify a minor current to a current with very high amplitude (power amplifier). it almost could be able to amplify 0.5A to 20A. and as my robot is a mobile robot, such...

or the other example could be...

Of course i can! I mean some kind of the scientific figures which are accurate in details like attached image. but about your suggestions... i am for example familiar with Inkscape but i did not find it so effective to generate high quality figures like attached one... furthermore I should...

Hi everyone! I need to draw a bunch of figures for my papers but i don't know how to use professional software like photoshop, 3dmax, maya, ...of course as you know, the figures must be pretty and accurate. i need to one which is powerful but simple to use does anyone has any suggestion...

Thank you very much. your correctness let's the functions be drawn!

Hi every one! I would like to draw a double integral function in related to R and h parameters by below M-File but It does goes wrong! Is there anyone to correct it for me? thank you syms R h; a1 = 0; a2 = atan(R./(R+h)); r1 = h; r2 = sqrt(R.^2+(R+h).^2); integrand =...
