IE2xx : Feedbacks and Dynamics

Prerequisites 
Linear Algebra

Contents:

This course can cover modeling of dynamic (time varying) systems, with applications in business, production-inventory and socio-economic systems. Course topics include:

  • Brisk review of Introduction to Dynamical Systems and Linear Dynamical Systems (Motivation through examples in business/ industrial settings); Modeling linear dynamical systems using ODEs; Solution characterization, solution methods for first, second, higher order ODEs; Characterizing higher order ODEs as linear systems
  • Motivating examples of dynamical systems with feedback
  • Laplace transforms. Transfer functions: Block diagrams, poles, zeros, delays
  • Stability, regulation, tracking and Controllability of dynamical systems.
  • Proportional, Integral, Derivative (PID) control 
  • Root locus design method: Perspective, procedure finding root locus, design using lead, lag, notch compensation 
  • Frequency-Response Design method: Frequency-response design method, Bode/ Nyquist plots 
  • State space method: System description, block diagrams, state equations and analysis
  • Discrete systems and non-linear systems  

The second part can focus on capturing industrial and social systems using dynamics equations/ system dynamics methodology, including:

  • Stock Management Structures and Industrial Dynamics
  • Models for social systems and economics
  • Simulation of linear and non-linear systems
  • Simulation of Discrete-time and Continuous time systems
