“…ANSYS is widely used to analyze piezoelectric transducer actuated smart structures in vibration control [18,22,36,103]. This commercial FE package can also be used to identify the open-loop dynamics of the controlled plant for AVC design; for example, Hong et al uses ANSYS to identify modal parameters for an ER fluid controlled frame in [39].…”

“…In figure 1, x r is the distance between the elastic base and the left end of the beam; u is the base displacement; m s, c s and k s are the mass, damping and stiffness coefficients of the elastic base, respectively, and f c is the control force. The equations of motion can be derived without difficulties and have been well documented in [15]. The equations of motion in the physical coordinates can be transformed to the modal coordinates by using the bi-orthogonality of the left and right eigenvectors to facilitate the control design in the modal space.…”

This study deals with the experimental micro-vibration control of a flexible beam mounted on an elastic base. The optimal independent modal space control (IMSC) is applied for modal decoupling of the system and design of the vibration controller. An optical sensor is employed for vibration feedback of the beam system, whereas a voice coil motor is utilized to serve as an actuator for micro-vibration control. The study demonstrates that excessive vibration in the micro level of the beam system can be successfully suppressed by the optimal IMSC approach and the hardware configuration developed in this work. An experimental proof has also been provided for the severe instability problem arising from the application of the approach proposed by the pioneer developers of the IMSC technique.

“…They found that the appropriate selection of parameters is important for successful controller design. Chu et al (2006) investigated the active vibration control of a flexible beam mounted on an elastic base using an independent modal space control. Experimental results demonstrated that this strategy was effective for vibration suppression of the beam system under disturbance.…”

Due to their extensive utilization in engineering designs, various vibration controllers have been investigated with design specifications in mind. The optimization of vibration controller designs is a complicated multi-criteria problem. In this paper, the mechatronic design quotient (MDQ) approach and genetic algorithm (GA) are coupled together to determine this optimal design solution. The MDQ is presented to formulate an evaluation function for the passive vibration controller design of flexible beam structures, and the GA is then used to maximize this function so as to achieve a design solution with the highest MDQ value. For comparison, both the MDQ performance of passive vibration controller design using linear dampers and active vibration controller design using a linear quadratic regulator are provided. The latter is used as the performance benchmark to evaluate the optimal design solution of the former. Experimental results show that the linear dampers design with the proposed method can achieve similar performance to an optimal active controller.
