    Abstract: A system for controlling transport of a liquid tank by an overhead crane and a method for transporting the liquid tank by the overhead crane, which can suppress sloshing of liquid in the tank, are provided. In the control of the overhead crane cart, the swing of a liquid tank and a suspender (16) that suspends the liquid tank from an overhead crane cart (14), and the sloshing of liquid in the liquid tank are modeled into a coupled system model, and the system is designed based on a mixed H2/H∞ control. method in which feedback control is executed using a swing angle (θ) of the suspender, a traveling command value of the overhead crane cart and an external force acting on the liquid tank are external inputs, and a difference (z) between a position of the overhead crane cart and a position of the liquid tank is the control amount, wherein an integrator or a low pass filter is used as a frequency weight function (W2) of H2 control, and wherein a frequency weight function (W28 ) of H∞ control is designed to cover a multiplicative error between the coupled system model, and a nominal model in which the sloshing of the liquid in the liquid tank is not taken into consideration.

    Abstract: A calculation code generation circuit performs calibration using a counter, and a digital correction circuit including the same. The calculation code generation circuit performs a calculation process according to first and second modes, the calculation process including generating a first code by sampling a first value of the count code, generating a second code by sampling a second value of the count code, generating first and second calculation codes using the first and second codes in the first and second modes, respectively, and generating, in a calibration disable state, a third calculation code using the first and second calculation codes generated in the first and second modes, respectively, to remove the influence of the comparison offset or comparison performance of a comparator, thereby removing a calibration error.

    Abstract: A linear motor has a tubular body and a rod that penetrates the tubular body in an axial direction, and is configured to displace the tubular body and the rod relative to each other in the axial direction. The linear motor includes: 12n+1 (where n is a positive integer) teeth arranged in the axial direction so as to project from an inner peripheral surface of the tubular body; 12n slots respectively formed between adjacent teeth of the plurality of teeth; 12n coils respectively disposed in the slots; and a plurality of permanent magnets held in the rod so as to be arranged in the axial direction. The respective coils are formed by being wound around an axis of the rod in an identical direction, and the number of permanent magnets positioned in the tubular body is set to 8n.
