ENSURING PIEZOELECTRIC DRIVE ROBUSTNESS USING THE METHOD OF CONTROLLED RELATIVE INTERVAL FREQUENCY
Annotation
The problem of ensuring robustness of precision positioning system with piezoelectric drive is considered for the case of the drive model with interval parameters. The proposed approach uses the concept of controlled relative interval frequency. It is shown that the problem can be solved with median modal control supplemented by a control over the relative interval state matrix of the designed system. An example of positioning system design with the use of proposed method is presented.
