| 41 | Motor control device | US14284900 | 2014-05-22 | US09306483B2 | 2016-04-05 | Haruyuki Suzuki |
| A motor control device controls a speed of a motor. The motor control device includes: a target speed generating unit that generates a target speed; a speed detecting unit that detects a current speed of the motor; a speed comparing unit that compares the target speed with the current speed to calculate a speed error; an error amplifying unit that amplifies the speed error and outputs a control value; and a motor driving unit that drives the motor in accordance with the control value. The error amplifying unit has proportional integral characteristics by which the speed error is amplified with a proportional gain and integration is performed in a lower frequency range than an integral corner frequency, increases the proportional gain as the current speed is higher, and shifts the integral corner frequency to a lower frequency as the current speed is higher. | ||||||

| An apparatus and associated methodology providing an axial positioner for a rotatable shaft that is selectively extensible along an axis of rotation. The apparatus includes a sleeve having a first race operably fixed in rotation with the shaft, and a second race operably fixed at a predetermined rotational position. The races define opposing bearing surfaces operably supporting the first race in rotation with respect to the second race. The apparatus also includes an indicia device attached to the second race. | ||||||

| In an instrumentation control system in which plural control devices are connected to each other through a network, and transfer of data is performed asynchronously, a reset switch is provided in one of a control device, and when this switch is depressed, an instruction to reset unreliable information in the respective control devices is transmitted to other control devices, the control device having transmitted the instruction and all the other control devices having received the instruction stop the reception of the unreliable information from the network for a definite period, the unreliable informations in the respective control devices are reset, and the unreliable informations in the whole network are reset. | ||||||
| 45 | Method for controlling oxidation in flue gas desulfurization | US798859 | 1997-02-11 | US6029100A | 2000-02-22 | Koichiro Iwashita; Susumu Okino; Naohiko Ukawa; Masaru Sakamoto |
| There is provided a method for flue gas desulfurization which is capable of conducting minute control of oxidation and which is capable of maintaining the concentration of sulfurous acid in an absorbent liquid within a proper range in a highly reliable and efficient manner, even in the case where an abrupt change occurs in the operational conditions of the system. In the method for controlling the oxidation in flue gas desulfurization, the value of proportional sensitivity K in the feed back control process, which is based primarily on the oxidation-reduction potential, is increased depending on the deviation .epsilon. in a region where the detected oxidation reduction potential value PN is below the target oxidation reduction potential value SN in correspondence with the characteristic change of the oxidation-reduction potential against the concentration of sulfurous acid. | ||||||
| 46 | Control system for transducer positioning motor | US197184 | 1980-10-15 | US4383209A | 1983-05-10 | Martyn A. Lewis |
| A control system for a stepper motor utilized in positioning a transducer in relationship to a plurality of parallel tracks on a record media. Dual closed loop feedback systems are provided. A current control circuit is provided having a high output impedance and a voltage control circuit is provided having a low output impedance. A switch may select the control sensor when the transducer is making coarse adjustments in position and may select the voltage control sensor when the transducer is making fine adjustments in position. A seamless switchover may be achieved where the voltage control sensor has a time constant which matches the time constant of the stepper motor. Performance is further improved by providing an impedance cancellation circuit which eliminates the internal resistance of the motor in order to quickly damp motionally induced emf of the motor. | ||||||
| 47 | Digital proportional plus reset process controller | US3575587D | 1966-02-07 | US3575587A | 1971-04-20 | MERGLER HARRY W |
| A direct digital process controller suitable for control of a single loop. The control algorithm characterizing the controller''s action corresponds to the conventional analog proportional plus reset case. However, what corresponds to the proportional effect is exercised by the controller at a greater frequency than what corresponds to the reset effect.

| PURPOSE: To reduce the temperature drift of a tachogenerator by rectifying the output signal of the tachogenerator so as to accord with the output speed signal of a digital differentiator which differentiates position signals in high speed above a predetermined speed. CONSTITUTION: A signal D'V which is obtained by differentiating position information pulse Ds is converted to an analogue signal e''v, and the output signal ev of a tachogenerator 4 is amplified to e'v by an arithmetic amplifier 10. When Ie'VI > E is formed, an AND circuit ANDi is operated, and if e''v is larger than e'v, clock pulse CP is added to the up input terminal 16a of a counter 16, and if smaller, added to the down input terminal 16b. A decoder 12 switches resistances Ri - Rn is consecutive order whenever the contents of the counter 16 increases by unit increment or decreases by unit decrement, and the gain of the arithmetic amplifier is controlled.
