1+ day, 4+ hour ago   (460+ words) Marine hydraulic ramps exhibit pronounced nonlinear behavior arising from configuration-dependent transmission geometry, gravitational torque, and servovalve flow–pressure coupling. Accurate angle regulation is further complicated by external disturbances and unavailable internal states. This study develops a nonlinear extended state observer…...
