Abstract

This paper presents a vibration control methodology that is useful in practical applications where the plant is difficult to model due to the presence of uncertainties or complex boundary conditions. The impedance control method uses a power flow approach wherein the controller is designed such that power flow into the structure is minimised. This is accomplished by using the dereverberated point impedance function at the actuator location for the design of the controller. The method is implemented for a composite beam with piezoceramic actuators. Simulations for the closed loop control are done using Matlab. Experimental correlation for the open loop transfer functions is presented. The impedance control method is compared with the velocity feedback and the independent modal space control (IMSC) methods. The results show that the impedance control method is superior to the other two methods in terms of vibration reduction.
