摘要： PROBLEM TO BE SOLVED: To provide a hydraulic jack control system capable of flexibly updating the control rules of a hydraulic jack according to the behavior of an object.
SOLUTION: The CPU 32 of a control computer 31 calculates a final control target value based on the present state (measurement information and calculation information) and the control rule when initial conditions such as the control rules are inputted therein. Moreover, the CPU calculates the control target value for each step to control the hydraulic jack in the same step until a deviation between the control target value of the objective step and an actual state comes within an allowable error range, and when it comes within the allowable error range, the processing is repeated from the next step. The control rules can be calculated based on the measurement values and specified values of any measurement channel and the calculated values and specified values of any calculation channel.
