Abstract: It is shown that it is possible in general to assign 2n poles of an axially vibrating nonuniform rod by sensing the state at n points along the rod and by using an actuator which applies the control force. Moreover, the ...

Abstract: Depending on the speed of rotation, a gyroscopic system may lose or gain stability. The paper characterizes the critical angular velocities at which a conservative gyroscopic system may change from a stable to an unstable ...
