Abstract:
An auto-tuner for developing a set of operational tuning parameters for use by a controller that receives a reference signal and that develops a drive signal to effect changes in an output variable, the auto-tuner comprising:a tuning parameter generator that generates a plurality of sets of tuning parameters for use by the controller during a tuning procedure;a test signal generator that delivers a test signal to the controller as the reference signal during the tuning procedure;a data collector adapted to receive measurements of an input variable and the output variable during the tuning procedure;a performance index generator that determines a performance index associated with each of the plurality of sets of tuning parameters from the measurements of the input variable and the output variable; anda tuning parameter selection unit that selects one of the plurality of sets of tuning parameters as the set of operational tuning parameters based on the performance indices.
