    摘要： A stop range setting circuit (1) sets a stop range of a control object on the basis of a target position signal, and a PBR (6) detects a present position of the control object driven by a motor (5). The comparison circuit (2) compares the present position of the control object with the set stop range, and outputs an out-of-stop range signal (e) and a rotating direction indication signal (f) until the control object reaches the stop range. The out-of-stop range signal (e) is input to a drive start determination circuit (3), and a drive permission signal (g) is output to a drive circuit (4) when the out-of-stop range signal (e) is continuously output for at least a predetermined period of time. The drive circuit (4) drives the motor (5) in a direction indicated by the rotating direction indication signal (f) while the drive permission signal (g) is continuously output, so that an instantaneous ON/OFF signal is not input to the drive circuit (4) in the presence of external noise.

    摘要： The position of tape loading and unloading mechanisms is determined using position switches whose output signals are coupled via a resistance network. The differences in voltage between different positions is small, thus making interpretation unreliable. The aim of the invention is to provide increased reliability, without the need for tightly toleranced network resistances or a high-stability network voltage. In a calibration procedure, the voltage associated with each individual position is measured at the network output, input into a memory and used as a target value for normal operation. The invention is applicable in particular to analogue or digital video or audio cassette recorders.

    摘要： A pulse generator includes a transducer (35) such as a resolver coupled to a driven body for converting a mechanical motion thereof to a phase-modulated signal, an excitation signal generator (33) for supplying an excitation signal as a carrier of the phase-modulated signal to the transducer, a clock pulse generator (31) for generating a train of clock pulses, a waveform shaping circuit (36) for shaping the wave form of the phase-modulated signal issued from the transducer, a counter (37) for receiving the clock pulses to form a content of count representing a time interval by which the output from the waveform shaping circuit being in a high or low logical state is longer or shorter than the corresponding priod of the excitation signal, a count pulse generator (39) for generating count pulses, a gate circuit (40, 44) for allowing the count pulses to enter the counter (41, 45) until the counter having contents of count corresponding to the time interval is initialized while the output from the waveform shaping means (36) is in its a succeeding low or high logical state, and an output gate circuit (42, 43) for issuing out the count pulses counted by the counter to issue out as a serial train of pulses.

    摘要： In an actuator control method and an actuator control device, time optimal control is used, and a switching time (t1) at which an acceleration output is switched to a deceleration output, and an end time (t2) of the deceleration output are calculated using a maximum acceleration (±p) and a maximum deceleration (±m) at the time of a maximum output of a control force, the control force of an actuator is set as a maximum acceleration output from the calculation time (t0) to the switching time (t1), the control force of the actuator is set as a maximum deceleration output from the switching time (t1) to the end time (t2), output of the control force is ended at the end time (t2), and the switching time (t1) and the end time (t2) are repeatedly calculated, and updated for each preset time, further, the control output is reduced along with decrease of residual energy, which is a sum of remaining work and kinetic energy of a control system. From this, an element of feedback control is incorporated in the time optimal control, and the control output is converged after the end of the control.

    摘要： Ein elektrischer Antrieb (2) wird von einer Antriebsteuerung (3) gemäß einem Beschleunigungsprofil (a(t)) von einer Anfangsposition (P1) zu einer Endposition (P2) verfahren. Das Beschleunigungsprofil (a(t)) weist bei der Anfangsposition (P1) einen Anstieg von 0 auf eine Maximalbeschleunigung (a1) und bei der Endposition (P2) einen Anstieg von einer Minimalbeschleunigung (a2) auf 0 auf. Zwischen der Anfangsposition (P1) und der Endposition (P2) weist das Beschleunigungsprofil (a(t)) einen Abfall von der Maximalbeschleunigung (a1) auf 0 und einen Abfall von 0 auf die Minimalbeschleunigung (a2) auf. Zwischen dem Ansteigen auf die Maximalbeschleunigung (a1) und dem Abfallen auf 0 sowie zwischen dem Abfallen auf die Minimalbeschleunigung (a2) und dem Ansteigen auf 0 verharrt das Beschleunigungsprofil (a(t)) während einer Haltezeit (T3, T4) bei der Maximalbeschleunigung (a1) und der Minimalbeschleunigung (a2). Der Abfall von der Maximalbeschleunigung (a1) auf 0 und der Abfall von 0 auf die Minimalbeschleunigung (a2) sind flacher als der Anstieg von 0 auf die Maximalbeschleunigung (a1) und der Anstieg von der Minimalbeschleunigung (a2) auf 0.

    摘要： A position control circuit having a demodulator with automatic tuning capability for use in an electro-hydraulic positioning system used to position a servo device. The position control circuit includes the demodulator, an analog to digital converter with an input voltage range, and a microcontroller. The demodulator has a gain and is operable to convert a feedback signal from the servo device to a position signal having a lower voltage value when the servo device is at its 0% position and an upper voltage value when the servo device is at its 100% position; the lower voltage value and upper voltage values being a function of the demodulator gain. Upon operator initiation, the microcontroller automatically calculates the largest value for the demodulator gain that results in the position signal from the demodulator having a lower voltage value within a lower voltage range and an upper voltage value within an upper voltage range, where the lower voltage range and the upper voltage range are within the input voltage range of the analog to digital converter.
