Training Simulator for Acquiring Operational Skill to Operate Overhead Traveling Crane while Suppressing Load Sway

Figure 4

Overview of proposed operation for suppressing load sway when using an impulse command input. (a) Command input regarding as the cart acceleration with (i) acceleration generated by pressing the momentary switch, (ii) deceleration generated by releasing the momentary switch, and (iii) acceleration generated by re-pressing the momentary switch. (b) Cart velocity. (c) Load sway occurred by the cart accelerations (i) and (ii). (d) Load sway occurred by the cart accelerations (i), (ii), and (ii).
