摘要： During the deceleration portion of a seek operation, the current level provided to the actuator motor of a disk drive is based on a desired linear deceleration versus time profile that has been temporally advanced by half of a servo data position sampling interval. At each position sampling interval, a new current level is determined and maintained for the interval between samples. The actual deceleration current follows a staircase curve centered on the desired profile so as to be self-synchronizing. The current level is also adjusted to compensate for the delay between obtaining a new servo data position sample and applying a new current level to the motor.

摘要： An apparatus for controlling the rotational speed of a motor. The apparatus comprises a subtracter for subtrating a speed error signal corresponding to a frequency signal generated from a frequency generator from a period deviation signal between the frequency signal and a predetermined reference frequency signal to produce a primarily compensated speed error signal; a first adder for adding the primarily compensated signal and the period deviation signal to produce an added signal; a delay circuit for delaying the output signal of the first adder, wherein the delay circuit comprises a first to an Nth delay cells, wherein each of the delay cells latches the output signal of the first adder entering the first delay cell and serially shifts the latched signal in each of the delay cells toward the Nth delay cell by one signal at a time whenever the output of the first adder is supplied to the delay circuit and wherein the output of the delay circuit is supplied to the subtracter and to the first adder; a summation circuit for summing up all of the signals being shifted from the respective delay cells to produce a sum period deviation signal; an averaging circuit for averaging the sum period deviation signal to produce an averaged deviation signal; and second adder for adding the primarily compensated signal and the averaged deviation signal to produce the motor speed control signal with a compensated period deviation. A method is also provided for controlling the speed of the motor.

摘要： A servo-motor control system varies a set point input signal to a comparator between predetermined limits in order to establish three detectable output conditions. When the difference between the feedback signal and the set point signal exceeds the average deviation of the set point input to the comparator, the comparator produces a characteristic output signaling rotation in one direction. When this difference signal is less than a negative quantity equal to the average deviation, the comparator produces a characteristic output which signals rotation in the other direction. If the difference signal is less than the absolute average value, then a third characteristic output is produced which causes a cutoff in the energization of the motor.

摘要： A size control apparatus for a machine tool having an in-process gauge device, a post-process gauge device, a calculating device and a compensating device. The post-process gauge device measures the workpiece machined under the supervision of the in-process gauge device and supplies the measured value to the calculating device. The calculating device derives an estimated value for a workpiece to be next machined from a predetermined number of measured values and ascertains a compensating value when the estimated value exceeds a control limit. The compensating device, when given the compensating value, shifts a null-point of the inprocess gauge device so that the finish size of the workpiece may be compensated.

摘要： Arrangement for synchronizing a measuring signal produced by a controllable generator with a reference signal. For motor speed control the generator is a system which is coupled to the motor shaft and provides a measuring signal the frequency of which is a measure of the motor speed. The arrangement includes a fourposition counter the count of which is increased one position by each reference pulse and is reduced one position by each measuring pulse. The arrangement further includes a sawtooth generator which provides a signal which is in synchronism with the reference signal and is applied to a logic circuit. This logic circuit is so controlled by the four-position counter as to provide an output signal which, after sampling at instants which correspond to the measuring pulses, produces a control signal which has an extreme value if the frequencies of the measuring and reference signals are different and has a value determined by the phase difference if the frequencies are equal. The great advantage of the arrangement is that the motor speed is adjustable over a wide range without stability problems arising.

摘要： Systems and methods are provided for using a Deep Reinforcement Learning (DRL) agent to provide adaptive tuning of process controllers, such as Proportional-Integral-Derivative (PID) controllers. The agent can monitor process controller performance, and if unsatisfactory, can attempt to improve it by making incremental changes to the tuning parameters for the process controller. The effect of a tuning change can then be observed by the agent and used to update the agent's process controller tuning policy. It has been unexpectedly discovered that providing adaptive tuning based on incremental changes in tuning parameters, as opposed to making changes independent of current values of the tuning parameters, can provide enhanced or improved control over a controlled variable of a process.
