Coupling between Sample Rate and Required Wordlength for Finite Precision Controller Implementation with Delta Transform

  title={Coupling between Sample Rate and Required Wordlength for Finite Precision Controller Implementation with Delta Transform},
  author={Hung-Ming Cheng and G. T-C Chiu},
  journal={2007 American Control Conference},
The delta-transform has been shown to have superior numerical properties in high sample rate controller implementation and signal processing. However, similar to controller design and implementation in the shift-operator, finite precision implementation introduced coupling between the required wordlength and the sample rate. As the sample rate changes, the locations of poles and zeros fluctuate from grids to grids. Insufficient precision of the processor may results in undesirable… CONTINUE READING
