Abstract :
Vibration control has been identified by wood products industry as one of the key technologies for increasing wood recovery in wood machining. This paper presents results of a research project for active vibration control of circular saws using magnetic actuators. An active control system is developed to increase wood recovery by reducing saw blade vibration. For online estimation and control of vibration characteristics, a state-space model is developed based on the finite element model analysis and experimental measurement. The characteristics of different vibration modes is estimated online by a Kalman filler based state estimator. A state feedback controller design is then implemented online and good clamping results have been achieved
