Design a control system to dampen the flexible modes of a smart structure.
This experiment consists of a flexible beam clamped at one end of the structure. The opposite end of the structure is equipped with a servomotor that drives an eccentric load. The objective is to dampen out the vibrations in the beam by driving the motor. The experiment includes the following components:
1) Base plate instrumented with a strain gage
2) Flexible beam
3) Motor and encoder. The motor drives the load through a gear ratio of 70:1. The encoder measures the angle using a 1024 count disc which in quadrature results in 4096 counts/rev.
4) Inertia load consisting of two rigid beams and a round crossbeam.
