Sliding mode active vibration control of circular saws

The sliding mode active vibration control system of circular saws is presented in this paper. Here, a novel control solution based on variable structure control using magnetic actuators is formulated, designed and tested in real wood cutting, for the control of the transverse vibration of the saw blade rotating at high speed. The sliding mode control system is developed to increase wood recovery for wood cutting by reducing the saw blade vibration and thickness and improving cutting accuracy. Real wood cutting control test results have shown a significant reduction of the vibration and thickness, which in turn means significant possible savings for the industry if the system is realized in industrial applications
