Design of Independent Modal Space Controller using Virtual Passive Approach

In this study, a new modified independent modal space control (IMSC), which relaxes the fundamental hardware limitation of IMSC, is suggested to handle vibration control problems using a virtual passive controller. This method has adapted a new stable switching algorithm between controlled modes and a virtual vibration absorber as a virtual passive controller in the independent modal space. It has been found that the new modified IMSC suggested in this paper, which can reduce the number of actuators, is shown to be simple and efficient in a realistic example of vibration control of a cantilever beam.
