Abstract:
The optimal control to a partially controlled turbogenerator
shaft torsional vibration system is investigated. The principle
of input feedforward control is presented to achieve the minimum
of the average vibration energy in a system，and
the optimal control matrix of the system is derived. A
turbogenerator shaft system is taken as an example to simulate
the optimal control process of the torsional vibration. Results
from this simulation indicate that the vibration can be
effectively controlled by a partial control strategy.
Key words:
Optimal control Partially controlled system Torsional
vibration Turbogenerator
