Latest Patents
Chase's latest patents include an actuator servo compensation method and a sampled-data control system exhibiting reduced phase loss. The actuator servo compensation method enhances the control loop for head position in rotating media data storage systems. This invention applies a compensation zero to the Position Error Signal (PES) before summing it with the integrator, effectively reducing transients caused by the integrator initialization step. This innovation minimizes overshoot and ringing in the actuator, thereby improving settling time and overall system performance. Additionally, the first sample velocity compensation scheme he developed removes the velocity correction factor from the PES signal after a seek, further enhancing system efficiency.
The second patent, a sampled-data control system, features a proportional integral derivative (PID) compensator. This system implements a digital differentiator that reduces phase loss as a function of frequency. The differentiator is designed to resemble an amplitude-balanced step function during a given sample period, which helps maintain system stability and performance.
