Objective:

The main objective of the Control System Laboratory is to introduce and enhance the knowledge and learning experience of students in topics encountered in Control Systems using advanced software tools like MATLAB which provide paths towards the engineering applications.

Some specific course objectives include:

• • Students will have a strong knowledge on MATLAB software.
• • Students will study the concept of time response and frequency response of the systems.
• • This course aims to familiarize the students with the modelling of dynamical systems, to simulate and analyse the stability of the system using MATLAB software.
• • Students will be able to analyse the physical systems represented in transfer function.
• • Students will be able to design controllers, compensators etc. using MATLAB software.

Overall, the Control System Laboratory aims to equip students with the practical skills and knowledge necessary to excel in the broad field of control system and related areas.
