Experimental Modeling prova


Thanks to the innovative methodology named NOSEM® (NOnlinear SEt membership Modeling), Modelway is able to design and develop mathematical models of complex and non linear systems directly from experimental data. In case of systems where physical laws are unknown or too complex to be modeled, the NOSEM® technology reduces time and costs of design.

Here below you can find some projects examples in which the application of a systematic NOSEM® approach allowed a significant reduction in the model calibration complexity, by having a development time reduction from months to weeks.

vertical-dynamics

Description: Development of algorithms for a mathematical model for Semi-active suspensions vehicle, in order to improve passenger comfort and vehicle handling.

Approach: Using NOSEM® technology has been developed a procedure for deriving, from experimental data, highly affordable nonlinear models of vehicles with semi-active suspensions. Such models are in form that can be used for the control design technique.

Value: Accuracy of the vertical dynamic model increased of one order magnitude. The use of NOSEM® technology in design and calibration of control permit an important time reduction of development. Control performances are increased by 10-25%.

high-power-laser-system

Description: Development of a mathematical model for Laser systems with highly nonlinear behaviors.

Approach: Using NOSEM® technology the model has been identified from I/O measurement on the real system overcoming the high nonlinear system behaviors difficult to model using a classical physical equation approach.

Value: quite accurate model has been obtained with a reduced design effort.
