Description The present study deals with the application of two different control Strategies viz. Direct Velocity Feedback (DVF) and Modified Independent Modal Space Control (MIMSC) to control the flexural vibrations of a cantilever beam mounted with piezoelectric patches. These two control strategies belong to two different categories viz. coupled control (DVF) and modal control (MIMSC). In case of DVF, the collocated system is inherently stable with respect to sensor/actuator (S/A) locations. For non-collocated system configuration, DVF is not considered to be suitable as stability of the system depends on S/A locations. With the help of root locus, it is shown that it is possible to achieve the stability of different modes provided the S/A locations are chosen properly. Also a comparison of DVF and MIMSC is carried out on the basis of two different criteria.
