Abstract
A method for the closed-loop control of a nonlinear controlled system in which a state variable of the controlled system is determined and an actuating value is determined using a control method and a reference variable. In addition, by using the state variable of the controlled system, a correction value is read from a linearization characteristic curve and multiplied by the actuating value and the product is specified as new desired value for the controlled system. The linearization characteristic curve is chosen in such a way that multiplication of the linearization characteristic curve by the nonlinear control action of the controlled system yields a linear control action.
