A simple nonlinear system is described within the Simulink environment.For control purposes, a sliding mode controller is designed in order to regulate the system to the origin. Furthermore, the chattering reduction has also been addressed with the introduction of tanh function.

There are 19 questions and 1 programming exercise. Some of them are very easy, some of them are really hard and challenging, and these will be marked as such. If you don’t want to be challenged too much, you can skip the hard questions
