“…The concept of phase compensation in vibration control has been presented by several researchers. Wie and Byun (1989) proposed a design procedure of a heuristic phase compensator using a second-order filter and showed design examples of mass-spring systems with uncertainties on spring constants. However, their designed compensators were not guaranteed to have 90° phase at the natural frequencies of modes to be controlled.…”

This paper addresses a phase delay control for controlling low-frequency vibrations of a lightly damped beam using a piezoelectric actuator and a piezoelectric sensor. This controller is designed to behave like the velocity feedback controller at the frequencies of modes to be controlled. This controller is composed of a lowpass filter, a highpass filter, and all-pass filters. The lowpass and the highpass filters arc supplemented for the robust stability of uncontrolled modes. The highpass filter also suppresses the amplification of the vibration around the frequency zero in the control system. The all-pass filters are designed to give desirable phase delay at the natural frequencies. The phase delay control is applied to vibration suppression of a cantilever beam with a piezoelectric actuator and a piezoelectric sensor. Experimental results show that the phase delay control works well.

In the present paper, helicopter rotor blades with adaptive airfoils are investigated considering discrete trailing edge flaps as well as continuous shape adaptation. First, a method for lagging mode stability augmentation is proposed and applied to a helicopter rotor with discrete trailing edge flaps located at the outer part of the rotor blades. Active damping enhancement of the aerodynamically weakly damped lagging modes defines the control objective subject to the requirement of robust performance with respect to the time-periodic system behaviour. A decentralized controller is proposed which is shown to be robust, conceptually simple and effectively provides damping enhancement. In the second part, we discuss continuous shape adaptation in order to overcome the disadvantages of discrete flaps. An Active Camber Rotor (ACR) with distributed active material components is proposed. Numerical simulations are presented demonstrating the aerodynamic effectiveness of shape adaptation.
