Course Objectives The course aims the students: i) to get a solid mathematical background on nonlinear systems’ equilibrium points, limit cycle and other nonlinear behaviors together with their Liapunov and input-output stabilities, ii) to gain skills of determining the existence, qualitative properties and stability of certain nonlinear behaviors for a given nonlinear system and iii) to have a nonlinear systems point of view.
Learning Outcomes The students who succeeded in this course;
  • Find equilibrium point(s) and limilt cycles of nonlinear systems
  • Linearize a nonlinear system to prove the Liapunov local stability of equilibrium point or a trajectory of a nonlinear system and decide the Liapunov stability in terms of eigenvalues of the Jacobian matrix.
  • Determine the bounded-input bounded-output stability of a nonlinear system.
  • Derive Liapunov function to prove the Liapunov stability of equilibrium point or a trajectory of a nonlinear system
Course Description Introduction to nonlinear phenomena: multiple equilibria, limit cycles, bifurcations, complex dynamical behavior. Planar dynamical systems, analysis using phase plane techniques. Describing functions. Input-output analysis and stability. Lyapunov stability theory. The Lure problem, Circle and Popov criterion. Feedback linearization and sliding mode control.
