Derivative Of A Function Calculator

This model simulates the position control of a DC motor. Parameters can be changed from the model properties tag.

Automatic differentiation is a technique for computing the derivatives of a function using the chain rule. Matlab objects make it easy to implement automatic differentiation. Note that this package is implemented in a rather old version of Matlab. You may need to edit it for newer versions.An...

The code computes the velocity profile for the vertical laminar flow of a Bingham fluid down a wall. As expected the profile is flat near the surface of the liquid film. In fact, we have a zero velocity gradient only when the shear stress is large enough (superior to tau0). This behaviour is...

The standard problem of a Two Link Manipulator is developed both kinematically and dynamically. It is then controlled to trace a rotated ellipse. The non-linear terms (like gravity/inertia etc.) are exclusively canceled out in varying degrees and the performance studied.This file was created as a...

Easy method to estimate the pile forces of a pile system. The program is very fast to run. This gives the engineer the possibility to try out a couple of different designs of the pile system in a quite small amount of time. The pile system is also plotted with the forces acting on it. This does...
