Control device and control program
A control device is connected to a servo mechanism that drives a controlled object and outputs a manipulated variable to the servo mechanism so that a controlled variable tracks a target trajectory. The control device includes a controller and a sensor. The controller acquires a measured value from the sensor and performs model predictive control for each control period using a dynamics model representing a relationship between the manipulated variable and the position of the controlled object to generate the manipulated variable to be output to the servo mechanism. The sensor measures the position of the controlled object. The controller performs model predictive control in a first mode using the measured value when the controlled object has a position within the range, and performs model predictive control in a second mode using an output value of the dynamics model when the controlled object has a position outside the range.
Coating Process and Quality Control of Coated Objects
A method for modelling a coating process including a plurality of coating parameters, includes the steps of: dispensing, by the coating process and during K work cycles, a coating on each of K pieces of objects to thereby obtain K pieces of coatings; recording, during each of the K work cycles, coating variable values of p coating parameters at M instances to thereby obtain recording results; and measuring at least one coating property at m locations of each of the K pieces of coatings to thereby obtain measurement results. The method is characterized by the step of determining a digital twin of the coating process on the basis of the recording results and the measurement results. By using results from a large amount of classical quality control measurements together with corresponding coating parameter information, a digital twin of the coating process can be determined through statistical processing of such big data. The digital twin) may be used either for automatic adjustment of the coating parameters to obtain an improved coating quality, for prediction of the coating quality right after a work cycle to obtain an improved quality control, or for both.

METHOD FOR CORRECTING TOOL PARAMETERS OF A MACHINE TOOL FOR MACHINING OF WORKPIECES
A method for correcting tool parameters of a machine tool for machining workpieces includes recording measurement values of measured characteristics as actual values of at least one workpiece machined with the machine tool.
