OVERHEAD CRANE CONTROLLING SYSTEM AND OVERHEAD CRANE CONTROLLING METHOD

摘要

PROBLEM TO BE SOLVED: To suppress vibration of a suspended load by a simple operation.;SOLUTION: An overhead crane controlling system has: a model calculation part 232 which calculates a model speed of a suspended load 6 conveyed by control object equipment on the basis of a control speed of the control object equipment based on a speed command value inputted via a push button switch and a ceiling crane system model; a control calculation part 231 which calculates a speed of the control object equipment so that the calculated model speed of the suspended load and a target speed of the suspended load are coincident with or approach each other, and outputs the calculated speed of the control object equipment as a control speed; and an actual control part 233 which controls an actual speed of the control object equipment on the basis of the outputted control speed. The target speed of the suspended load is a control speed, and the model calculation part 232 repeats calculation of the model speed of the suspended load and output thereof to the control calculation part 231 on the basis of the control speed calculated and outputted by the control calculation part 231 and the ceiling crane system model.;SELECTED DRAWING: Figure 3;COPYRIGHT: (C)2018,JPO&INPIT
