• A Kalman Filter for Nonlinear Attitude Estimation Using Time Variable Matrices and Quaternions 

      Deibe Díaz, Álvaro; Antón Nacimiento, José Augusto; Cardenal, Jesús; López Peña, Fernando (MDPI, 2020)
      [Abstract] The nonlinear problem of sensing the attitude of a solid body is solved by a novel implementation of the Kalman Filter. This implementation combines the use of quaternions to represent attitudes, time-varying ...
    • A time-varying Kalman filter for low-acceleration attitude estimation 

      Deibe Díaz, Álvaro; Antón Nacimiento, José Augusto; Cardenal, Jesús; López Peña, Fernando (Elsevier, 2023-03-15)
      [Abstract]: This work shows an attitude estimator (AE) based on a time-varying Kalman filter (TVKF) and adapted to those cases where a low-acceleration assumption can be applied. This filter is an extended version of a ...
    • Potential and Limitations of an Improved Method to Produce Dynamometric Wheels 

      Bueno-López, José Luis; Cardenal, Jesús; Deibe Díaz, Álvaro; García de Jalón, Javier (MDPI, 2018)
      [Abstract:] A new methodology for the estimation of tyre-contact forces is presented. The new procedure is an evolution of a previous method based on harmonic elimination techniques developed with the aim of producing ...
