Application of Linearization Clan in Fan Model
Fan is widely used in the industrial process, but fan usually have complicated nonlinear characteristics .The stronger degree of nonlinearity is, the bigger deviation between the model and actual process is. The performance of conventional linear controller will be significantly stepped down with enhanced nonlinearity of the controlled process. Many practical applications need the model of fan to be linearized. And the result is scribed in the paper which adopts the theory of linearization clan to deal with the relationships of the flow and pressure on nonlinear fan model. First, fan is given as a nonlinear object, and then is processed by using the linearization clan method, to get a series of linear models segments. These linear models are superimposed to describe the nonlinear model. Simulation results show the method of linearization clan can approximately describe the nonlinear system of fan, and it has good operability and value of application.
