Abstract :
A new computationally efficient filtering algorithm for reconstruction of the first harmonic of a periodic signal is presented. The algorithm allows to recover the combustion quality information from the engine speed measurements which are noise contaminated. The algorithm is applied to the torque estimation problem for a V8 spark ignition engine.
