Latest Patents
DuLaney's latest patents include a method and apparatus for closed loop acceleration control for a data storage device motor. This invention involves identifying a first commutation state of the rotor and executing a Proportional, Integral, and Derivative (PID) control routine for closed loop control of the rotor's acceleration. The process optimizes loop gain values through voltage feedback, allowing for precise control of the motor's acceleration from a stopped position to an intermediate velocity.
Another significant patent focuses on motor acceleration using a continuous sequence of current limit values. This method accelerates a motor to operational velocity by utilizing a series of discrete current limit values, which establish maximum current magnitudes over various intermediate velocities. The continuous sequence is derived from coefficients of a multi-order polynomial curve, resulting in faster acceleration, reduced current spiking, and less acoustic noise during operation.
