Abstract: | A new computationally efficient filtering algorithm based on the Kaczmarz projection method for reconstruction of the first
harmonic of a periodic signal is presented. The algorithm allows the recovery of combustion quality information from noise-contaminated
engine speed measurements. The algorithm is verified using a spark-ignition six-cylinder engine in the torque estimation problem. |
