Modeling control processes using only positive values

In this work, we are proposing a model that improves closed loop automatic controllers for real time processes, using only a positive function to deal with the process variations, no matter if they are positive or negative, the unit uses the sign to deal with the control output value. The first part of this document, gives an introduction to the kind of control systems that can be applied, and the reason to make this project. The second part gives the parameters to be used on the control model, as well as the signal conditioning stage. Then at third part, the design of the model is explained, followed by Results and conclusions at fourth and fifth parts respectively.
