Abstract : "This paper develops an extended-state-observer-based sliding mode control strategy for continuous casting
mold oscillatory system driven by servo motor in the presence of matched and mismatched disturbance. Extended
state observers are employed to estimate the compound disturbances, and the requirement of the derivative
of the compound disturbances to zero is avoided. In order to counteract the mismatched disturbance and attenuate
the chattering phenomenon, a novel sliding surface based on extended state observer is designed for the system.
Simulation results illustrate that the proposed controller can achieve better tracking performance and robustness to
the compound disturbance."
