“…In order to avoid phase error of the two successive demodulated signals, variable area-type capacitive encoder has been presented in [9][10][11][12][13][14][15][16][17]. In [10][11][12][13][14][15][16], the stator plate has been designed by multiple conductive segments and it is faced parallel to the similar structure of RP. Thus, the angular position of the RP is determined from the overlapping area of stator and rotor segments.…”

“…Researches either focus on developing new types of encoder or improving the accuracy and precision of existing ones. Examples of researches where new types of encoders are devised can be seen in [1][2][3], [I] looks at the development of a hybrid micro laser encoder that can detect displacements relative to an external grating scale with great resolution, [2] works on a new kind of rotary encoder based on magneto-optical storage while [3] describes a capacitive linear encoder characterized by its untethered slider. This work looks at the second area of research on encoders which is improving the accuracy and precision of the measurements of an existing encoder, [4][5][6][7] research on this also.…”

The accuracy of measurements from a rotary encoder is of high importance and the level of accuracy desired will depend on the nature of the application in which the encoder is used. Due to the various errors in the rotary encoder measurement during real-time usage, this work has designed a LabVIEW program that exempts erroneous readings that are not within the chosen range, forms an array of readings within the acceptable range and finds the mean of the array once the size of the array is equal to the chosen size of the array stipulated in the program. This mean value is given as the actual measurement.This gives a more accurate real-time measurement than is the case without the program. A motor-generator set frequency measurements is used to validate the effectiveness of this program and frequency readings on the inverter driving the motor are compared with that displayed on the system through the program. Some analyses are carried out in order to ascertain the dependency of the accuracy of the measurements acquired on the array size utilized in the program.
