What is it about?
The article is about optimizing the design of a nonlinear robust control algorithm for an electrohydraulic servo system using an Ant Colony Optimization algorithm. The control algorithm is based on the coefficient diagram method and backstepping strategy, and it includes a nonlinear observer to handle uncertainties and external disturbances in the system's supply pressure. The article presents a systematic design process for achieving stabilization and angular displacement tracking, and demonstrates the effectiveness of the proposed optimization method through numerical simulations.
