摘要

In this article, the issue of position-tracking control of servo system with external disturbance is studied. A novel hybrid second-order sliding-mode control (HSSMC) strategy is proposed. To be specific, first, the uncertainties of motor parameters and load torque are considered as lumped disturbance, and an adaptive extended sliding-mode disturbance observer (AESMDO) is designed in order to esti...
