For analog control, a simple PD scheme with sensors and actuators on the main rigidbody, with control relying on separation between control bandwidth and the lowest elastic frequency, and fully flexible modal control based on LQG programs are studied. For digital control, a problem for sampled sensor signal (at constant sample interval) digital logic and actuation is formulated by a zero order sample and hold device (at constant sample rate). 收起
