Latest Patents

John B Resman holds a patent for an "Adaptive control technique for a dynamic system." This invention describes a controller designed for a voice coil motor-driven disk file actuator. The device features an online adjustable gain characteristic that controls the movement of the actuator assembly. It includes an estimator that accurately estimates actuator velocity and bias. The forward gain is estimated from position and coil current measurements, which are then compared with a nominal value to create an error signal. This error signal is utilized to adjust the controller and estimator gain characteristics. The control technique allows for changes in the open-loop system without affecting the closed-loop performance. By monitoring loop gain, it is possible to alter compensator gains to maintain a constant closed-loop performance.
