Study targets:
The main aim of this course is introduction to methods of modeling flexible mechanics structures in order to optimization of placement of sensors and actuators. The robust control design of space modes will be follow.
Content:
The course is focused on advanced control of mechanical structures with a nonnegligible flexibility. All the presented methods for control design will assume availability of a mathematical model obtained using finite elements method (FEM). Discussed will be the topics of vibration attenuation, both passive and active, feedforward and feedback control, collocated and noncollocated control, and shaping the input signals. The tasks of control design will be formulated as optimization tasks, namely H optimization, including some structural constraints on the controller.
