Nonlinear Systems Estimation in Renewable Energies

Abstract

In this work, nonlinear system used in renewable energies is dealt. These nonlinear systems can be described by blocksoriented. Lately, these types of models are increasingly used practically [1-4]. Nonlinear systems estimation parameters are a necessary step in control [5-7]. The nonlinear element can be in input of system (Figure 1) or in output of system (Figure 2). If the two blocks are parametric, the determination of parameters nonlinear system can be done using quite a few solutions e.g. [14]. When both parts are parametric, the identification problem has been dealt with using several methods e.g. [1,8-10]. Twostage nonlinear parameters estimation solutions, involving two stages, have been established in e.g. [1,8-10]. Presently, a solution nonlinear parameters estimation is dealt. The considered nonlinear system has a nonlinear element in output of system (Figure 2).
