All-pass filters as a tool for converting a positive feedback to a negative feedback when controlling weakly damped systems
Original language description
The problem of active vibration control of weakly damped mechanical structures is potentially unstable modes of vibrations due to the positive feedback for some vibration modes. The paper will discuss the change of positive feedback on the negative one using all-pass discrete-time filters which are arranged in a cascade. The piezoelectric actuator as a source of force is used to damp vibration. It is well known that this actuator type has hysteresis.
