Time-delay control of an undamped two mode system [electronic resource] /
Abstract (Summary)Summary: Attenuation of residual vibration caused by the reorienting of a structure is of great importance in dynamic applications. Generally speaking, common methods of vibration attenuation include slow maneuvering of the structure or the addition of damping to the system. Optimal trajectory generation and feedback control may also be used to limit system excitation. However, these methods are typically inefficient and do not produce adequate system performance. The goal of this thesis is to design a time-delay control method for minimizing residual vibration of dynamic systems. The time-delay control method, referred to as proportional plus multiple delay (PPMD) control, involves the use of multiple time delays in conjunction with a proportional gain to cancel the dynamics of a multiple mode system in a robust fashion.
