The decrease of production and maintenance costs of a product as well as increase in the efficiency are no doubt few of the major trends in industry. One way of achieving these goals is to design products that require less material to build and have stricter tolerances. The vibrations may cause severe wear and tear and structural fatigue that result in increased maintenance costs as well as pose a severe limitation on how strict the design tolerances can be.

In Roteva project new passive, semi-active and active vibration control methods are designed for different kinds of processes. The processes to be studied include: vibrations of a paper winder, vibration isolation on high speed blower and suppression of vibrations of a conveyer belt system.

The research in the project is carried out by three different TKK departments. The research done by the control engineering group is focused on development of generic semi-active and active vibration control algorithms. The processes that are being studied havesignificant non-linearities and parameter uncertainties. These features have to be taken into account as the control law is being designed.

The control methods to be studied and applied in this project include: modified LQ-control, non-linear state-feedback control, robust and adaptive control and sophisticated control methods for semi-active control (variation of process parameters)
