The Faculty of Engineering at Universidad de La Sabana, in Colombia has three undergraduate programs: Agro industrial Production Engineering, Industrial Engineering and computer engineering and a graduate program: Specialization in Environmental Engineering and for the development of the Faculty in Long and medium term, it has been looking into research projects and technological development to integrate all the programs at once. The development of projects in the area of virtual instrumentation aimed at automation and process control and agro-industrial production is the core of this development.
The unit operations laboratory has met the basic needs for teaching and research faculty. However, it has become necessary to update and modernize the installed capacity with new tools and methods to achieve automation and control at the operations unit laboratory. Currently, there are different suppliers on the market as National Instruments and Siemens which offer a wide variety of products for industrial process automation software and hardware level. The costs of these products are considerably higher.
As a strategy to reduce costs by automating the unit operations laboratory at the University of la Sabana propose the use of Labview software with control elements, calculation and control governed by microcontrollers, which reduce costs significantly. The project

This project seeks to apply new methods and strategies of control and automation, such as the use of microcontrollers and virtual instrumentation software, such as Labview. Getting the objectives of this project will allow us to deepen in different lines of research and technological development, including: System identification, control of SISO and MIMO systems, software design of Control and Automation, Industrial Control, and also, monitoring industrial networks, robotics, artificial intelligence, fuzzy control, neural networks, etc.. In which the faculty would be able to involve more people, as mathematicians, engineers, chemists, etc.
2 Scope It is proposed that this project be implemented in stages (WBS is shown in the Appendices A): • First stage: Design and build the convection forced drying tunnel • Second stage: the system will be placed on electronic devices and mechanisms to sense and act on the controlled variables (temperature, relative humidity, flow, etc. ). • Third step: Strengthening the physical concepts required for successful acquisition of the signals from the physical plant by installing the equipment and software necessary for project development. It will look familiar with the basics of programming in object-oriented language (Labview).
And there will be the design of data acquisition systems and finally implemented. • Fourth step: Identifying the type of system to be controlled through techniques to determine the constants involved in the model. • Step Five: Once the mathematical model is known of the control, it would be design a control strategies by using a simulation software (Matlab) and finally, based on the results of the simulations, the controllers will be placed on a real systems (microcontrollers and Labview). At this stage it is implicit implementation of the necessary adaptation of a power module on the actuators of the system.
