【摘要】 针对振动主频大范围、快速变化,并伴有大量宽频干扰和噪声的复杂振动环境,结合干扰观测器,改进了多模型切换方法(MMST)进行主动隔振(AVI),避免了对整体系统的建模和辨识,设计了新的切换指标函数,减轻了计算负担。最后通过模拟仿真验证了该控制方法的可行性和优越性能。更多还原

【Abstract】 Considering complex vibration environment characterized by extensively and rapidly varying dominant frequency and broadband disturbance/noise,the Multiple Model Switching Tuning(MMST) control method by disturbance observation is modified to realize active vibration isolation(AVI).The overall modeling and identification of a vibrational system are avoided,the novel switching index function is presented to alleviate computation burden.At last,the feasibility and the superiority of the presented method are demonstrated by simulation.更多还原
