Model Predictive Parameter and State Estimation and Optimal Sensor Placement


Project Description

In this subproject we consider the online and self-calibrating identification of relevant parameters in transient thermo-elastic FE models. These parameters can include, for instance, heat transfer coefficients as well as heat inputs due to the machining process and electrical drives. Their knowledge is of paramount importance in particular for the subprojects developing online correction strategies. We will develop model-predictive parameter and state estimation schemes, which are using a moving time horizon to adapt the estimated parameters and state to measured temperature (or, when available, displacement) data.

These techniques will be developed under the specific operating conditions of machine tools, i.e., having available only a limited number of measurements, high dimensional thermo-elastic FE models, and they will take into account the pose dependence. Parameter models developed in other subprojects will serve as so-called background information and stabilize the estimation process. Initial experiments are showing this procedure to be very robust and capable of reconstructing time-dependent changes in heat transfer coefficients by means of only a few temperature measurements. In actual machine geometries, it will be important to place the temperature sensors intelligently, and we will further develop our optimal sensor placement techniques in order to make best use of the available sensors also in these nonlinear identification settings.
