Course Objectives

  1. For the students to become familiar with some modern control theories and techniques, such as state space representation of the different dynamical systems, solution of the state equation, state transition matrix, controllability and observability, pole placement design, state observer and Lyapunov stability analysis.

Course Outcomes

At the end of the course students will be able to
• Represent different dynamical systems in state space form
• Solve the state space dynamical systems to get the transient response with different inputs.
• Check the system two important properties such as controllability and observability.
• Design the state feedback control law for regulation as well as for tracking problem.
• Design the full order and reduced order observer
• Check the stability of the dynamical systems using Lyapunov method
