摘要： A method and apparatus for compensating for the asymmetrical phases of a spindle motor in a disc drive are provided. With the apparatus and method, compensation values are learned by sampling speed data during a period of operation of the disc drive where the speed is stable and only one control operation is performed per revolution of the disc. The sampled speed data is used to generate the compensation values for each of the phases of the spindle motor. The compensation values are stored in a compensation mechanism which is used by the spindle motor speed controller to provide compensation for the asymmetrical phases of the spindle motor. During Normal operation, the actual speed output of the spindle motor is measured and is subtracted from a reference speed to generate a difference speed value. Based on the corresponding electrical phase, the correct compensation value is fetched and is subtracted from the difference speed value to obtain a compensated difference speed value. A control signal based on this compensated difference speed value is generated and provided to the spindle motor to thereby control the output speed of the spindle motor.

摘要： A motor control circuit for controlling rotation of a motor includes parallel first and second controller paths (gears). Each path includes a proportional and integral (PI) controller and a digital to analog converter (DAC). The DACs operate over different dynamic ranges (gains). The respective PI controllers have different control parameters to provide a common frequency response. The first controller path is used to output motor control signals to control the application of drive current to the motor. The circuit switches to the second controller path once the first controller path operates within a selected tolerance of a minimum or maximum level of the first dynamic range. The final state of the first PI controller is used to configure the initial state of the second PI controller to eliminate transients. The use of different gears allows the circuit to adaptively accommodate large variations in motor current and spindle motor configurations.

摘要： A method and storage device are provided for initializing a polynomial linearizer in the storage device. The linearizer is initialized by identifying the coefficients of the linearizer polynomial. To reduce the computational intensity of this process, orthogonal-type coefficients for at least two orthogonal polynomials are identified, where the linearizer polynomial is formed as the sum of the orthogonal polynomials. The orthogonal-type coefficients are then combined to identify linearizer coefficients for the linearizer polynomial.
