Title: Innovations of Huawei Zhou in Fault-Tolerant Control Systems
Introduction
Huawei Zhou is a prominent inventor based in Jiangsu, China. He has made significant contributions to the field of control systems, particularly in fault-tolerant methods for linear motors. With a total of three patents to his name, Zhou's work is recognized for its innovative approaches to enhancing the reliability and performance of electrical systems.
Latest Patents
One of Zhou's latest patents is the "Fault-tolerant direct thrust-force control method for five-phase permanent-magnet linear motor with one open-circuit phase fault." This method involves deriving the generalized Clarke transform matrix and its inverse based on fault-tolerant phase currents. It also includes deducing stator fluxes in the α-β plane and defining virtual stator fluxes to obtain compensatory voltages. The actual stator voltages are calculated using a modulation function of a voltage source inverter, allowing for the estimation of thrust-force and virtual stator fluxes.
Another notable patent is the "Fault-tolerant field-oriented control method of five-phase interior permanent-magnet linear motor under two nonadjacent short-circuit phase faults." This invention proposes a method that maintains the magnetic motive force constant before and after two-phase open-circuit faults. It utilizes an internal mode controller and a back-EMF observer to transform a nonlinear strong coupling system into a first-order inertia system. This method effectively restrains thrust force fluctuations caused by faults while preserving dynamic and steady performance.
