This paper proposes a modified swing control for a nonlinear inverted pendulum system by utilizing the sliding mode controller based on the on-line tuningBeesalgorithm as speed of optimization and accuracy of results. The goal of the proposed nonlinear controller is to obtainthe optimal force control action for the pendulumcart in order to stabilize the pendulum in the inverted positi... https://macorners.shop/product-category/dog-tag-necklace/
