Definitions
- the present invention relates to a rotation control device and a rotation control method, and more particularly, to a rotation control device that controls the speed of a rotating body when rotating various rotating bodies using a mainspring, an engine, electric power, human power, and the like. It relates to a rotation control method.
- the machine train energy at the time of opening of the mainspring is converted into electric work energy by a generator, and the electric work energy is used to operate the rotation control means to control the current value flowing through the coil of the generator.
- An electronically controlled mechanical timepiece that accurately drives the hands fixed to the timepiece and displays the time accurately is described in Japanese Patent Publication No. 7-111912.
- a signal based on the rotation of the generator rotor is input to the counter, while a signal from the crystal oscillator is also input to the power counter, the values of these power counters are compared, and the difference is calculated.
- the rotation speed was controlled by controlling the generator based on the This counter compares the phase difference between the reference clock pulse (Ref pulse) and the generator rotation cycle pulse (G pulse). If the G pulse advances, the U / D counter counts down, and if it is late, the U / D counter counts down. It had a counter count and was composed of a so-called integral force counter.
- the generator is braked and R The brake was held until the time measurement for one cycle of the ef pulse was completed. Therefore, the value of the integration counter sets the brake release time. In other words, the value of the integration counter was integrated with the brake release time N so that the average speed of the G pulse matched the target speed (Ref pulse). In other words, this system employs integral control.
- the average speed of the rotor over a sufficiently long time must be adjusted to the set time because signals output at each cycle are counted and compared by a counter.
- it was possible to control the speed of the needle at an average speed it was not possible to immediately adjust the rotation speed of the rotor, resulting in low responsiveness.
- the integral control can be represented by the block diagram of FIG. It is known that the transfer function commonly used for generator Z motors is l Z s (s T + 1). As shown in FIG. 26, this is composed of a transfer function 60 1 with a first-order lag of 1 / (sT + 1) and an integral term 60 2 of 1Z s. Therefore, the generator itself to be controlled includes the integral element.
- Figures 27 and 28 show Bode diagrams assuming that only integral control is performed on this control target.
- the conditions under which the rotation control is stable are that the phase margin, that is, the phase at a gain of 0 db (gain intersection) is more than 180 °, and that the gain margin is It is necessary that the gain at 180 ° (phase crossing) is 0 db or less.
- the phase is delayed by 90 ° in the control object and the phase is further delayed by 90 ° by the integral control. 8 0. It has a phase characteristic in the vicinity. For this reason, it is difficult to achieve stable control because the phase margin and gain margin cannot be obtained only by integral control. For this reason, the timepiece disclosed in Japanese Patent Publication No. 7-111980 must be controlled at a fairly low frequency, resulting in a response of about 0.16 Hz or less.
- Figure 28 shows a case where the gain of the integration counter is multiplied by 10 °. Also in this case, the phase margin is delayed by more than 180 °, and stable control cannot be expected.
- the timepiece uses a mainspring as power, the rotation force changes greatly depending on the degree of winding, and a control error occurs, so that the timepiece is delayed or advanced.
- acceleration of the rotor and the like is generated by the movement of the arm, which disturbs the control state and causes fluctuations in the movement of the hands, leading and lagging. There were also problems.
- a first object of the present invention is to eliminate a phase deviation of a rotating body and to provide a control system. It is an object of the present invention to provide a rotation control device and a rotation control method in which the response of the system is fast and which is strong against disturbance. :

Therefore, so-called phase-locked loop control, that is, PLL (Phase-Locked-Loop) control can be realized. For this reason, for example, since the brake level can be set by comparing the rotation signal waveforms of the rotating body for each period, once the signal is pulled into the lock range, unless the signal waveform fluctuates greatly instantaneously, Realizes a stable control system with fast response In addition, the phase deviation can be eliminated.

- the clocks 1 4 3 input to the frequency difference detection circuit 1 2 3 are counted until the falling edge of.
- the output 144 of the first counter 144 outputs the value held at the falling edge of the target signal 113 until the next falling edge.

- the role of the frequency difference compensation means 114 will be described with reference to FIG. If there is no frequency difference compensating means 1 1 4, the control loop is composed of only the phase difference compensating means 1 18, but the time constant of the mechanical body 1 1 1 is about 1 second as described above, so the phase difference compensating filter

- the rotating body 103 slowly setstles from the high-speed rotation state to the rotation speed synchronized with the target signal 113. From a clock user's point of view, it takes more than 10 seconds for the movement of the second hand of the clock to settle down, causing anxiety. This response time can be reduced to about 1 second, which is the response time of the machine body 111, by the frequency difference compensating means 114. This is because the frequency difference control loop is stable even when the loop gain is very large.
- FIG. 8 shows the switching signal 129 divided into four signals. That is, a control start signal 54, a frequency control valid signal 53, a sample signal 52, and a phase difference control valid signal 51.

- the present invention is not limited to watches, toys, and automobiles, and can be widely applied to those requiring speed control of a rotating body.
- the frequency difference compensating means includes a frequency difference compensating holding means for holding a frequency difference compensating signal, and the brake control means immediately after starting the rotation control And a steady control stage in which the rotation control is stabilized.
- the rotation control is performed by a frequency compensation signal of a frequency difference compensating means.
- the brake control is performed by the addition signal of the frequency difference compensation signal held by the frequency difference compensation holding means and the phase difference compensation signal. For example, even when the rotation speed of the rotating body is largely deviated from the target rotation speed, the rotation speed can be quickly approached to the target rotation speed, and the rotation control can be performed with good responsiveness.
- control start stage when it is determined from the frequency difference that the rotation control has been stabilized, the control can be appropriately switched regardless of the variation of the rotating body.
- control start stage the control can be switched with a simple circuit configuration by switching from the control start stage to the steady control stage by regarding the state as stable when a predetermined period of time has elapsed from the control start.
- the circuit configuration can be simplified and the size can be easily reduced. Can be easily incorporated.
- the rotation control device and the rotation control method according to the present invention are useful for controlling the speed of various rotating bodies with high accuracy and speed. It is suitable for use in rotation control devices incorporated in small devices such as watches.
