Positioner, gravity correction device and gravity correction method

摘要

This invention regards the positioner. The aforementioned positioner at least one position sensor and, at least has with one position control section and one position operation device at least. The aforementioned position sensor measures the position of the suffering position control control equipment. The aforementioned position control section uses the measurement signal which is offered by the aforementioned position sensor as the input signal. The output signal which is formed and by the aforementioned position control section is used in order to control the position of the aforementioned suffering position control control equipment with the aforementioned position operation device. The aforementioned positioner furthermore has the gravity correction expedient which revises the gravity which operates the aforementioned suffering position control control equipment. The aforementioned gravity correction expedient, at least has with one gravity correction control section and one gravity correction operation device at least. The aforementioned gravity correction control section uses the output signal which is formed by the aforementioned position control section forms the output signal as the input signal. The description above the output signal which is formed is used in order to revise the gravity which operates the aforementioned suffering position control control equipment with the aforementioned gravity correction operation device.
