APPLICATION OF SIMULTANEOUS FEEDBACK CONTROLLER FOR FREE AND FORCED ACTIVE VIBRATIONS CONTROL
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 5, Issue 5
Abstract
Evergrowing customer demands and thus the manufacturing methods have become the backbone of global competition for a wide range of products. This has led to the development of intelligent, compact and lightweight smart machine tools. A great difficulty is faced in the design of such machine tools due to the fact that the reduction in weight results in low rigidity and poor vibration control characteristics. The induced vibrations in the system may destabilize the system and result in complete failure of the system. On the other hand, the successful vibrations reduction of the smart machine tools during machining process can improve productivity, increase quality, and reduce tool wear. Also healing the vibration error can reduce industrial waste, save money and improve design flexibility of new cutting tools. Therefore, there is a need to develop machine tools that are equipped with suitable vibration control features. Smart machine tools, technology using active control system may provide a solution to this problem. These machine tools use piezoelectric materials, electro-rheological fluids and shape memory alloys as sensors and actuators for providing effective vibration control.This paper presents the design and application of simultaneous feedback controller for controlling the free and forced active vibrations.
