Opis (srp)

Research within the doctoral dissertation is focused on thedevelopment and improvement of the reliability and performance ofpseudorandom position encoders. One of the goals is to find an optimalsolution for the code reading system, which, in combination with thewidth and arrangement of the code tracks on the encoder disc, enablesa higher degree of reliability and flexibility in the operation of theencoder. Sources of optical encoder errors affecting the accuracy of themeasured angular position were analyzed. A reliable method ofdetecting code reading errors has been applied and the way the encoderworks in the event of errors or failure of parts of the code readingsystem is defined. Different solutions of serial pseudorandom tonatural converters were analyzed and compared using simulations andimplementations in the LabVIEW FPGA environment. Solutions withshorter code conversion times are presented. A solution for reliabledetermination of the zero position when mounting the encoder on themotor shaft is presented. Three experimental pseudorandom encodersystems were implemented using glass and plastic discs, as well asdifferent code reading systems. An integrated optical sensor withseveral photodiodes was used, as well as a commercial optical moduleintended for use with incremental encoders. Algorithms of encoderoperation were tested with simulated bits of pseudorandom sequence,as well as with real signals from experimental systems. Thefunctionality of the encoder was tested and confirmed under normaloperating conditions, as well as when code reading errors occur.
