1. A control system for a turbine engine assembly, the control system comprising:
a controller programmed to control operation of the turbine engine assembly and to determine a trim configuration to balance a rotating engine structure associated with the turbine engine assembly, the controller including a processor and a memory for storing information indicative of operation of the rotating engine structure, wherein the controller is programmed to determine the trim configuration by:
receiving information from one or more sensors within the turbine engine assembly that is indicative of an out of balance condition of the rotating engine structure, wherein the information includes a speed of a rotating engine structure, tracked vibration magnitude and a tracked vibration phase angle for the rotating engine structure;
analyzing data provided by the one or more sensors to determine a veracity of the provided data and assigning a quality score based on the determined veracity, wherein the determination of data veracity is based on a stability of a signal received from the one or more sensors, wherein sensor stability is a measure of a signal remaining constant for a predetermined time;
storing the information and the quality score as a data set in the memory that corresponds with one of a predefined number of engine operating ranges, wherein the predefined number of engine operating ranges comprise multiple ranges of engine rotational speeds;
providing a means of selecting one or more stored data sets for use in determining a trim configuration; and
generating a new trim configuration based on selected ones of the data sets.
