Abstract: This article suggested a new interruption estimator sliding-mode-control (IESM) technique for the nonlinear perturbed processes. In this, the proposed control law is designed using an output of the interruption estimator. The effect of modelling uncertainties and external disturbances are effectively counteracted using an interruption estimator approach. The detailed stability study is discussed to prove the stability and robustness of the presented control scheme. Comparative simulation results are rigorously discussed to verify the effectiveness and applicability of the proposed scheme on the inverted pendulum, identical-tank, and asymmetrical process examples.

Keywords: asymmetrical process; interruption estimator; inverted pendulum; identical tank; sliding mode control; SMC.
