Black hole–inspired control of servo-hydraulic systems

A pioneer control methodology is presented for servo-hydraulic systems, inspired by the dynamics of black holes, namely by designing a Black Hole inspired Controller (BHC) and a Fuzzy-BHC hybrid controller. Our findings underscore the effectiveness of this astrophysics-inspired controller in tracking step, sigmoid and sinusoidal trajectories, tuned via a black-hole-inspired metaheuristic optimizer, even disturbance scenarios, including those due to unmodeled friction. BHC achieves lower tracking-error indices than conventional PID and sliding-mode controllers, with a maximum reduction of approximately 60%.
