摘要： A method and apparatus are provided for estimating and/or precluding stick-slip, or other oscillatory or resonant behavior, through use of a virtual transducer, which precludes the need for having sensors located adjacent to a driven element of the system, or adjacent contact surfaces at which the stick-slip relative motion may occur. Parameters measurable at a drive mechanism are utilized for controlling a system in a manner which precludes stick-slip, or other oscillatory or resonant behavior, of the driven element. Relative motion between contacting surfaces in the driven element, prone to stick-slip behavior, is controlled such that, after sufficient force is applied by the drive element to overcome static friction forces between the contacting surfaces and break them free from one another, relative motion between the surfaces is maintained at a high enough relative speed that the surfaces are precluded from statically contacting one another, so that stick-slip behavior is precluded.

摘要： Presented is a harmonic regulator that regulates a plurality of individual harmonics in a system having periodic torque disturbances to commanded values, including zero. For each harmonic being regulated, a feedback signal having at least one harmonic component due to the harmonic being regulated is transformed from a source reference frame to a harmonic reference frame of the harmonic being regulated to form a qd feedback signal. The qd feedback signal is subtracted from the commanded value to form a qd signal and regulated. The regulated qd signal is transformed to a destination reference frame to form a compensation signal and the compensation signal is added to a control signal to form a qd control signal that drives each harmonic being regulated towards the commanded value.

摘要： There is disclosed an apparatus and method to reduce total harmonic distortion input into a 24 -pulse autotransformer system and the autotransformer system itself. The 24 -pulse autotransformer system is configured to receive an input of a first voltage and produce an output voltage of a second voltage. The system includes a pair of autotransformers coupled to an AC power source. One winding of each phase of the first autotransformer has a turn ratio to effect a decrease in the voltage across said winding over a symmetric voltage value and a second winding of each phase of the first autotransformer has a turn ratio to effect a decrease in the voltage across said winding over a symmetric voltage value, thereby reducing total harmonic distortion (THD) in the input current to the system without a zero sequence blocking transformer.
