Yz. Tsypkin et al., IDENTIFICATION OF LINEAR-SYSTEMS IN THE PRESENCE OF PIECEWISE POLYNOMIAL DISTURBANCES, IEE proceedings. Control theory and applications, 143(4), 1996, pp. 305-308
The paper proposes a method of performing system identification of a l
inear system in the presence of bounded disturbances. The disturbances
may be piecewise parabolic or periodic functions. The method is demon
strated effectively on two example systems with a range of disturbance
