Control Engineering Syed Sohail Ahmed Assistant Professor, UET Taxila

Course Objectives Course Objective: This course strikes the balance between theory and practice. While the undergraduate student needs a firm foundation in the theoretical aspects of the subject, it is also important that he or she be exposed to real world of engineering design. The reason for this approach is twofold. First, an introduction to real world problems serves as an motivating factor. Second, it eases the transition from academia to industry.
