Introduction
Qing Wei Jia is a notable inventor based in Singapore, recognized for his contributions to disk drive technology. With a total of 3 patents, he has made significant advancements in the field, particularly in the areas of actuator control and resonance attenuation.
Latest Patents
One of his latest patents is titled "Disk drive determining frequency response of actuator near servo sample frequency." This invention involves a disk drive that includes a servo control system designed to manage an actuator for positioning a head over a disk. The system samples servo sectors at a specific frequency to generate a position error signal, which is then filtered to produce a control signal. A discrete-time sinusoid is added to this control signal to determine the frequency response of the actuator effectively.
Another significant patent is the "Method and system for robust attenuation of mechanical resonances using a multi-rate low pass filter." This invention provides a digital low pass filter that effectively attenuates high-frequency resonances in control signals. The filter is characterized by a transfer function that includes a phase-advanced factor, which helps to avoid unstable poles, ensuring stability in the system.
