# Linear System Theory

By Prof. Ramkrishna Pasumarthy   |   IIT Madras
This course will provide a thorough introduction to the theory of Linear Systems with emphasis on Control related concepts. First, mathematical models describing the fundamental properties that govern the behavior of systems will be developed. We will cover time invariant, time varying, continuous and discrete time systems. This course will cover concepts of stability, controllability, observability, design and serve as necessary foundation for further study in the area of systems and control.
INTENDED AUDIENCE: Graduate Students from Electrical/ Mechanical/ Aerospace / Chemical Engineering PREREQUISITES: 1) Linear Algebra 2) Differential Equations 3) Control Systems Engineering

Learners enrolled: 1041
