  • Publication number: 20180207740
    Abstract: An arc sensor adjustment device and adjustment method for carrying out highly-accurate copying control. A welding system includes a welding torch, a welding power source that supplies power to the welding torch, a robot and a robot controller that cause the welding torch to oscillate, and an arc sensor that obtains a welding current or a welding voltage generated during welding while oscillating the welding torch. The arc sensor obtains a welding current or a welding voltage generated during calibration, in which welding is carried out while oscillating the welding torch in an up-down direction, calculates, on the basis of the obtained welding current or welding voltage, a correction amount for the position of the welding torch during welding carried out while oscillating the welding torch in a left-right direction, and applies the calculated correction amount to copying control.

  • Patent number: 9033662
    Abstract: A control apparatus C of a horizontal axis wind turbine apparatus WTG calculates the value en of a pitch angle command for each blade based on the rate of change ?D of the azimuth angle ? of a Nacelle N and the rotor azimuth angle of the blades B1, B2 and B3, causes the rotor R to generated torque around the yaw axis by periodically controlling the angle change of the pitch angle of the blades B1, B2 and B3, and using that torque, controls the rate of change of the azimuth angle of the nacelle N. The value of that angle change is calculated as a value that increases as the inputted value of the rate of the change ?D increases.
