Abstract: A system is configured for machining a workpiece (100), the workpiece includes an interior surface (110) that defines an internal passage (112). The system includes an electrode (116) located within the internal passage and electrically isolated from the workpiece, an electrolyte supply, a power supply, and a remover. The electrolyte supply is configured for circulating an electrolyte in a gap between the electrode and the workpiece. The power supply is configured for applying a voltage between the electrode and the workpiece to facilitate smoothing the interior surface. The remover is configured for completely removing the electrode from within the internal passage after smoothing the interior surface.

Abstract: A wind turbine includes multiple blades, multiple Micro Inertial Measurement Units (MIMUs) for sensing parameter signals of the blades, and a control system. The control system includes a blade bending moment calculation unit, a blade bending moment error signal calculation unit, and a pitch angle compensation command calculation unit. The blade bending moment calculation unit is used for calculating blade bending moment values of the blades based at least on the sensed parameters. The blade bending moment error signal calculation unit is used for calculating blade bending moment error signals of the blades based on the calculated blade bending moment values of the blades and multiple blade bending moment commands. The pitch angle compensation command calculation unit is used for calculating pitch angle compensation commands of the blades based on the calculated blade bending moment error signals to adjust pitch angles of the blades respectively.
