This laboratory is associated with the subject of computer control, which is taught to students of the fourth stage in all branches of the department. The laboratory is equipped with a range of software, such as MATLAB, which is used to carry out laboratory experiments, which are conducted in the laboratory with a total of 9 hours per week and an average of 10 students per class. This laboratory aims to introduce students to the following topics:

   1. An introductory study of the MATLAB program and its applications.
   2. Studying methods of conversion between control systems for continuous and discrete times.
   3. Studying the stability analysis of digital control systems.
   4. Studying the design of digital compensation systems.
   5. Studying the discrete state space model.

In this lab, laboratory lectures are given within the engineering design subject associated with the Microcontroller PIC for the fourth stage students of the Control and the Mechatronis branches.

The laboratory helps the students of the fourth stage to accomplish their projects and apply them practically. In addition, the laboratory contributes to the manufacture of some laboratory equipment of the department and providing assistance to other departments of the university in the field of specialization.

The Computers Control Laboratory is specialized in training the students on how to use the computer program (MATLAB) in the applications of the computers control subject. Moreover, the lab assists in training the students on how to use the instructions of the MATLAB software and record the results and values. The result is the preparation of qualified engineers with knowledge of how to deal with different systems and control these systems using the (MATLAB) software.

The laboratory aims at:

1 - providing students with the basic principles and skills to deal with systems using the (MATLAB) program.

2 - developing these skills through the experiments offered to students by performing experiments and discussing them from scientific and engineering perspectives.
