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

    【課題】簡単な操作で吊荷の振れを抑制することを課題とする。【解決手段】押しボタンスイッチを介して入力された速度指令値に基づく制御対象機器の制御上の速度である制御速度と、天井クレーンシステムモデルとに基づいて、制御対象機器によって運ばれる吊荷6のモデル速度を算出するモデル演算部232と、算出された吊荷のモデル速度と、吊荷の目標速度とが一致又は近づくよう、制御対象機器の速度を算出し、該算出した制御対象機器の速度を制御速度として出力する制御演算部231と、出力された制御速度に基づいて、制御対象機器の実速度を制御する実制御部233と、を有し、吊荷の目標速度は、制御速度であり、モデル演算部232は、制御演算部231で算出され、出力された制御速度と天井クレーンシステムモデルとに基づいて、吊荷のモデル速度を算出し、制御演算部231へ出力することを繰り返すことを特徴とする【選択図】図3
