Nonlinear Adaptive Control for Slewing Flexible Active Structures

Wilson, D.G.; Starr, G.P.; Parker, G.G.; Robinett, R.D.

A robust nonlinear adaptive control (NAC) system was designed for the rotational slewing of an active structure. The control laws were developed for both motor torque control and beam vibration control actuation. The experiments validated the control system performance. Robustness to parameter variations were tested increasing the tip mass, that reduced the first-mode bending frequency. It was found that the control system performance results were similar to the zero tip mass case.
