A pragmatic controller for a gantry crane
Journal of Physics: Conference Series, 2021 Abstract A gantry crane presents a control problem with ten state variables. The undamped swinging of the load has led earlier researchers to apply cumbersome control strategies. The essence of pragmatic control is gleaned from autopilot designs of half a century ago.
