Sliding mode control for a double integrator system

A basic SMC model for position control of satellite with 2nd order system.

Equation used is J*theta_ddot = u. Model is developed to get an idea of how SMC works , how it converges and what is chattering. Tweak the parameters and see the change in response of SMC. For more detailed equations and understanding read cited book. Kindly don't forget to rate the file.
