Control systems

By Prof. C. S. Shankar Ram   |   IIT Madras
Course Objective: To provide a basic understanding of the concepts and techniques involved in designing control schemes for dynamic systems.
Learning Outcomes: At the end of this course, one should possess in-depth knowledge of concepts from classical control theory, understand the concept of transfer function and use it for obtaining system response, analyze dynamic systems for their stability and performance, and design controllers (such as Proportional-Integral-Derivative) based on stability and performance requirements.

INTENDED AUDIENCE: Undergraduate engineering students (electrical engineering, electronics engineering, mechanical 
                                        engineering, aerospace engineering, chemical engineering)
PREREQUISITES:          2nd year undergraduate students in engineering. Prefer that they have completed a course on engineering
                                        mathematics that teaches complex variables and laplace transform.
INDUSTRY SUPPORT:   Automotive companies.

Learners enrolled: 3819
