EXTENDED STATE-SPACE MODEL AND OUTPUT PREDICTION

Popis výsledku v původním jazyce

Most methods of advanced controller design are based on the description of a system behavior in some mathematic form. The static characteristic of such a linear model goes through the origin of coordinates e.g. if input is zero then output is zero too. In the case that the controlled system hasn?t this feature the deviation form of the model is used. Controller with deviation model requires additional recalculations of measured, manipulated and set point variables and it complicates the controller implementation at the end. In the paper it is shown a simple extension of continue- and discrete-time state-space model into the form that allows applying original values of all variables if the static characteristic doesn?t pass through the origin of coordinates. Derivation of the extended model is demonstrated on a linearization of nonlinear model. An extended model application is shown on example of the system output prediction equation which is necessary for predictive controllers design.
