METHOD AND APPARATUS FOR NON-MODEL BASED DECENTRALIZED ADAPTIVE FEEDFORWARD ACTIVE VIBRATION CONTROL |
摘要 |
A method and system/apparatus implementing a non-model based Decentralized Feedforward Adaptive Algorithm (DFAA) for active vibration control of an actively-driven element, such as an Active Vibration Absorber (AVA) (24). The AVA (24)preferably includes an inertial tuning mass (42) and a voice coil assembly (46) and is contained in an active vibration control system (20) wherein the method and system/apparatus reduce vibration of a vibrating member (22) at an attachment point (26) by receiving an error signal from an error sensor (28) such as an accelerometer and a reference signal from a tachometer (32) or accelerometer (34), where the reference signal is correlated to, or indicative of the frequency content of, a primary vibration source (36) and calculating an updated output signal via an electronic controller (39) using the non-model based DFAA to dynamically drive the actively-driven element, such as AVA (24). The method and system/apparatus using DFAA is effective for reduction of both tonal and broadband vibration. The method approaches the performance of Filtered-x LMS control, yet is decentralized and does not require information regarding the plant. |
