<p>Solving numerical prediction position sensing encoder enables the design of rotating parts of the system and measuring the instantaneous position of a moving part, which is based on the management of the oscillator according to the value of differential rotation speed derived from the passage through the rotating part of its fixed position. This purpose is achieved by the instantaneous position of the numerical value is derived from the pulse voltage controlled oscillator (5) and because calibration counter range is the final value of the counter pulse (2) after the arrival of the pulse sensor fixed position (1) compared with a value of digital comparator (3). The resulting figure is the comparison of both figures led to terminal (12) production control voltage circuit (4). Depending on the value at terminal (12) production control voltage circuit (4) generates the control voltage, which is introduced into the terminal (14) voltage-controlled oscillator (5). This voltage is adjusted frequency voltage-controlled oscillator (5) so that its value varies depending on the value of the output of the comparator (3) to achieve a zero difference in this terminal. Signal from the voltage-gated oscillator (5) is guided to the input (16) of the divider 1: n, which will reduce the frequency signal in the rate of 1: n, which is used to progressively download counter value (2) and result reading (19) is the numerical value of the instantaneous position of the rotating system.</p> |
