Nonlinear Control of a Parametrically Excited System Subject to Actuator Saturation
Lei Chen, Colin H. Hansen (2003)
Proceedings of the 42nd IEEE Conference on Decision and Control, DecemberAbstract:
In this paper, a control method that combines linear and nonlinear velocity feedback control is proposed to suppress the principal parametric resonance in a flexible cantilever beam structure. Linear-velocity feedback is employed for bifurcation control and cubic-velocity feedback is employed to suppress the high-amplitude vibration. Numerical simulation and experimental results show that combined bifurcation control and nonlinear feedback control can avoid actuator saturation and performs better than linear-velocity and cubic-velocity feedback control alone.
