sliding mode:In this project, a sliding mode controller is designed to a linear plant with non-linear dis- turbances. The performance of the designed controller is then veried via simulation using MATLAB and Simulink. Then, the sign function in the designed controller will be replaced by a sat function, and the performance of the new controller will be investigated. Finally, some conclusion remarks will be made according to the simulation results.
