And Control

A Hard Disk Drive (HDD) is an inexpensive mass-production product, but the head-positioning control systems of HDDs require nanometer-scale positioning performance. Therefore, we have studied head-positioning control systems of HDD using designs which integrate mechanical and control systems to improve their control performance while curbing cost increases. In this paper, we introduce “disturbance suppression in high-frequency ranges through phase stable design for high-order mechanical resonances” and “high servo-bandwidth design through mode shape design of mechanical resonance” as examples of techniques that have been developed and are easily applied to products.

Functional Transformations

The strategy for managing the process of sustainable development is reduced to the need for periodic implementation of structural and functional transformations in the objects of the regional economy, arising from the objective appearance of qualitatively new challenges (disturbances) from society and nature. At the same time, the design of new and reconstruction of existing facilities with a long service life (more than 20 years) should be aimed at the preventive elimination of challenges not only of the present, but also of the future. Long-distance calls need to be predicted and taken into account in order to reduce the overhead of object evolution. The problem of reconstruction of urban treatment facilities together with a control system is considered in order to ensure their operability in the face of uncertainty of future challenges.
