Latest Patents

One of Lei Zuo's latest patents is focused on active control vibration isolation using dynamic manifold. This innovative controller for multi-degree-of-freedom (DOF) active vibration isolation effectively accounts for plant uncertainties and payload disturbances through dynamic frequency-shaped sliding control. The approach involves modal decomposition, which reformulates a multi-DOF vibration control problem into a series of modal problems, allowing for the extraction of modal parameters. The design targets specific frequency-domain performance, such as a skyhook, which is redefined as a frequency-shaped sliding surface. The examination of boundary layer approximation reveals that robust skyhook performance can be achieved. Furthermore, the manifold extends to adaptive vibration isolation without model reference, enabling control without the need to measure excitation or know mass, stiffness, and damping matrices. This patent also allows for control of plants subjected to disturbances beyond vibration, applicable to any system described by equations similar to those governing mechanical dynamic systems.

Another notable patent by Zuo is the steam turbine packing spring. This invention consists of a flat, elongated spring body with specified dimensions, a flange at one end, and at least one bend located substantially midway along the length of the spring body. This design enhances the efficiency and reliability of steam turbines.
