Method and system for determining operating performance parameters of a device

A system for determining operational performance parameters of a device, the system comprising:

• device mounted sensors;
• at least one processing unit configured to generate an output parameter set, the at least one processing unit being configured to generate the output parameter set comprising the at least one processing unit being configured to:
• measure a first parameter set during operation of the device using the device mounted sensors;
• provide a computer-implemented supplemental model and determine a second parameter set by the computer-implemented supplemental model;
• combine parameters of the first parameter set with at least one selected parameter of the second parameter set, such that a hybrid parameter set is obtained;
• provide the parameters of the hybrid parameter set to a Kalman-Filter-module;
• predict, by the Kalman-Filter-module, a third parameter set by a second model being equivalent to the hybrid parameter set regarding the respective parameter types;
• compare, by the Kalman-Filter-module, the parameters of the hybrid parameter set and the third parameter set;
• estimate, by the Kalman-Filter-module, an output parameter set;
• determine a deviation between respectively one distinct parameter of the first parameter set and an equivalent parameter of the second parameter set;
• provide a correlation between deviation values and covariance values for at least one parameter of the third parameter set;
• determine a covariance value from the correlation based on the determined deviation;
• and
• forward the covariance value to the Kalman-Filter-module for estimating the output parameter set;
• and
• a display configured to display at least one parameter of the output parameter set or a modified parameter based on the output parameter set to a user.
