PDF-Chapter Nonlinear feedforward control

1 Basic ideas of feedforward control A basic control problem is to generate a control signal so that the output of a physical system follows a given reference signal The simplest con64257guration is shown in 64257gure 111 where is the controlled sys. Nonlinear Model Problem Let us consider the nonlinear model problem 87228711 f in 8486 1a 0 on 8486 1b where is a given positive function depending on the unknown solution As usual is a given source function which we for simplicity assume not to 6 Linearization of Nonlinear Systems In this section we show how to perform linearization of systems described by nonlinear dif ferential equations The procedure introduced is based on the aylor series expansion and Di64256erentiating 8706S 8706f Setting the partial derivatives to 0 produces estimating equations for the regression coe64259cients Because these equations are in general nonlinear they require solution by numerical optimization As in a linear model Viscoelastic Material Analysis.
