Recent developments (2015)• System identification and control of laboratory scale

micro-grid within renewable energy sources • Remote monitoring and control of a 4-tank didactic

platform• Development of hardware-in-the-loop techniques for

intelligent renewable energy conversion systems

36ni.com

Conclusions• Real benefits of the program implementation have been observed, given the high

interest shown by the students and their positive reaction• Seen as a good way to blend academic theoretic and practical training with useful

skills for the workplace

• Using virtual instrumentation for homework and project for subsequent courses (e.g. Control Engineering using software libraries from the Control Design and Simulation module), bachelor and master theses

• Impulse for active involvement in further workshops, courses and on-line training and other activities on the topic of virtual instrumentation and data acquisition systems

37ni.com

Outlook• Better promotion of specialists in virtual instrumentation among

companies that apply these technologies e.g. through internships• Increasing the attendance and promotion rate of the CLAD

examination• Encouraging students to pursue further training levels: CLD, CLA and

student involvement in promoting the use of virtual instrumentation andgraphical system design

• New curriculum – Major update integration• Increase collaboration with other LabVIEW academies: regional

and worldwide
