Simulation and analysis of duffing oscillator using sliding mode control

Sliding mode control is one of the most robust nonlinear control schemes among many nonlinear controllers due to its robustness property and ability to decouple systems in lower dimensions. In order to overcome the known or bounded uncertainties many nonlinear controllers can work well, however, some of them fails to capture the unbounded uncertainties. The modeling of a real time system plays a vital role in mechanical system engineering. The exact modeling of a system is essential in order to analyze the behavior of the system. This article analyze the sliding mode control (SMC) behavior for nonlinear models and nonlinear uncertainties.
