  • Electroerosion apparatus drive control system employing fuzzy logic
    Patent number: 6064920
    Abstract: An apparatus and method is provided for tuning a controller parameter of a PIV controller with a position, velocity and/or integral controller element for a control path of a drive in an electroerosion apparatus, with the help of a fuzzy controller, wherein for the purpose of tuning, a preset control input distribution, such as a time-dependent distribution of the position of the drive, is provided to the PIV controller as input variable and wherein an input variable of the fuzzy controller is derived from the control variable of the controller. Additional input variables of the fuzzy controller are derived from a controller output of the PIV controller.

  • Method and apparatus for controlling a brushless electro motor by determining the absolute phase position of the rotor relative to the stator
    Patent number: 5874821
    Abstract: The invention relates to a method for controlling an electric motor, in particular of a brushless electric motor, whereby the absolute phase position of a rotor in relation to a stator of the electric motor (4) is determined, and to an apparatus for the method. A characteristic feature of the invention is that one or several movement(s) of the rotor are excited, the absolute phase position of the rotor in relation to the stator is measured, and the absolute phase position is deduced therefrom.
