    • A control load such as a cylinder or the like is driven at a constant speed by controlling the flow rate of a variable delivery pump. The control mode is switched to the pressure control to keep the stop pressure constant on the basis of an increase in pressure when the control load stops. A remaining delivery amount which will be necessary to raise the delivery pressure to an object stop pressure when the load stops and an excess delivery volume due to the operation time lag when it is assumed that the delivery by the pump is stopped at the present time are predicted. When they coincide, the delivery amount of the pump is set to zero and the control mode is switched to the pressure control. On the other hand, the product of a load volume and a fluid compressibility is calculated from the increase in pressure when the load stops. The feedback gain of the pressure control is controlled on the basis of the calculated value of this product. Further, the pressure difference and the designated flow rate are compared and either smaller one of them is always set to the designated value of the flow control.
    • 通过控制可变输送泵的流量,以恒定的速度驱动诸如气缸等的控制负载。 控制模式切换到压力控制,以便在控制负载停止时基于压力增加来保持停止压力恒定。 当假设当前停止泵的输送时,在负载停止时将输送压力提高到物体停止压力以及由于操作时间延迟的过量输送量所需的剩余输送量是: 预料到的。 当它们重合时,泵的输送量被设置为零,并且将控制模式切换到压力控制。 另一方面,当负载停止时,从压力的增加计算负载体积和流体压缩性的乘积。 基于该产品的计算值控制压力控制的反馈增益。 此外,比较压力差和指定的流量,并且将其中的较小的一个总是设置为流量控制的指定值。

    • Controlled variable table data, which consist of pulse number data corresponding to the maximum controlled variable of a fluid valve and divided into N divisions in each of which given pulse number data are set, are stored in a memory so that the sum of the given pulse number data in the N divisions may be equal to the number of pulses for giving a given controlled variable to the fluid valve. On the other hand, period table data, which consist of pulse interval data divided into divisions corresponding in number to the divisions of the controlled variable table data for determining a given control pattern, are stored in another memory. The fluid valve is controlled by successively generating pulses corresponding to the pulse number data in the individual divisions of the controlled variable table data at pulse intervals set in the individual divisions of the time length table data, driving a pulse motor by means of the generated pulses to control the flow rate and fluid pressure, counting the pulses, converting the count into an analog signal, thereby driving an actuator for the fluid valve.

    • The driving speed of a hydraulic actuator is feedback controlled by adjusting an amount of fluid by a digital valve having a valve which is opened and closed by a pulse motor. For speed control, the deviation between a set speed of the actuator which is set by a speed setting device and a detection speed of the actuator which is detected by a speed sensor is obtained. A pulse signal of a frequency proportional to the magnitude of the deviation is generated. When the deviation is positive, the pulse motor is driven using the pulse signal as a CW command pulse. When the deviation is negative, the pulse motor is driven using the pulse signal as a CCW command pulse. The rotational amount of the pulse motor is the integral of the pulse frequency which is proportional to the deviation.
    • 液压致动器的驱动速度通过由具有由脉冲电机打开和关闭的阀的数字阀调节流体的量来反馈控制。 对于速度控制,获得由速度设定装置设定的致动器的设定速度与由速度传感器检测的致动器的检测速度之间的偏差。 产生与偏差大小成比例的频率的脉冲信号。 当偏差为正时,使用脉冲信号作为CW指令脉冲驱动脉冲电机。 当偏差为负时,使用脉冲信号作为CCW指令脉冲驱动脉冲电机。 脉冲电机的旋转量是与偏差成正比的脉冲频率的积分。

    • The bidirectional transmission to write or read out data is executed between a read/write unit and a memory module by the contactless electromagnetic coupling using induction coils. A spread spectrum communication technique is used in at least the up transmission to transmit data from the memory module to the read/write unit in the bidirectional transmission. Two kinds of chirp waves or M series having little correlation are used in the spread spectrum communication. For instance, in the case of using the chirp waves, on the transmission side, two kinds of chirp waves having little correlation are prepared and either one of the chirp waves is transmitted in correspondence with the data bit 0 or 1. On the reception side, the correlation between the reception signal and each of the reference values of the two kinds of chirp waves which have previously been stored is calculated and the data bits 0 and 1 are demodulated on the basis of the result of the calculation. Further, a frequency code signal including a combination of a preamble, a terminator, data, and a terminator is used in the down transmission from the read/write unit to the memory module.
