Active vibration absorbers using generalized PI and sliding-mode control techniques

摘要: This article deals with the design of passive and active vibration absorbers combining absorbers, differential flatness Generalized PI sliding-mode control techniques to attenuate harmonic vibrations affecting a mechanical system. Two different schemes are considered, one employing only position measurements mass carriage be controlled (dynamic feedback controller) other using excitation frequency feedforward controller). The controllers developed in context an off-line prespecified reference trajectory tracking problem. Some numerical simulations included illustrate response dynamic performance closed loop
