Identification of Different Discrete Models of Continuous Non-Linear Systems. Application to Two Industrial Pilot Plants.

The continuous industrial plants dynamically working inside a large operating range involve non-linear phenomena that mostly cannot be suitably approached by linear models. In order to describe their behaviour, it is then necessary to use non linear models and/or variable parameter models. The control of such systems can be managed from adaptive methods or multi-model techniques but it may be preferable to try to find a global non-linear model correctly describing the system behaviour in all its operating conditions and a unique control law. Moreover, the goal being the control by means of one or several digital processors, it is necessary to build a discrete non-linear and/or time-varying parameter model.
