    • A feedback control device capable of continuously performing high-accuracy, stable control even in cases where any of multiple controllers for controlling a controlled system becomes incapable of control action. A controller (master controller) generates control data for stably controlling a heater by feedback control, controls the heater in accordance with the control data, and sends the control data to the other controller (slave controller). The slave controller receives the control data from the master controller but does not control the heater while the master controller is operating normally. If the master controller develops anomaly and becomes incapable of normal control action, the slave controller initiates feedback control of the heater in accordance with the control data received from the master controller immediately before the anomaly occurred, and controls the heater thereafter in accordance with control data generated thereby.
    • 即使在用于控制受控系统的多个控制器中的任一个变得无法控制的情况下,也能够连续执行高精度,稳定的控制的反馈控制装置。 控制器(主控制器)通过反馈控制产生用于稳定地控制加热器的控制数据,根据控制数据控制加热器,并将控制数据发送到另一控制器(从控制器)。 从控制器从主控制器接收控制数据,但在主控制器正常运行时不控制加热器。 如果主控制器出现异常并且不能正常控制动作,则从控制器根据在异常发生之前从主控制器接收的控制数据启动加热器的反馈控制,并根据控制数据控制加热器 由此产生。

    • In the thunder cloud observation system of the present invention, the vertical direction accumulated water content (VIL) is calculated by the VIL arithmetic operation unit from echo strength data obtained by the climate radar, the echo peak temperature is obtained by the echo peak temperature arithmetic operation unit with reference to altitude-temperature comparison data on the basis of high atmospheric climate data, the precipitation area is determined by the area determination unit from the VIL data, and the thunder cloud area generated within the precipitation area is identified from the echo peak temperature data. The thunder cloud area determined by the area determination unit is subjected to the correlation processes in terms of distance and overlapping area by the identification/tracking process unit, thus performing the identification/tracking, and the results of the processes of the area judgment unit and the identification/tracking process unit are displayed in the image display unit. Therefore, even a thunder cloud area regionally generated within a cloud expanding at a relative low altitude can be identified, and the area thereof can be detected and tracked.

    • A bypass controller (30) controls ON/OFF of a three-way electromagnetic valve (62) according to a detection value of a cam chamber sensor (12a). When the cam chamber sensor (12a) detects a viscosity of lubricant exceeding a predetermined allowable value, the three-way electromagnetic valve (62) is controlled to turn ON so that the output side of an oil separator (13) communicates with a bypass route (61). The pressure in the cam chamber (12) is reduced to or below the atmospheric pressure by suction of a compressor (16) with a check valve (14) regulating the pressure in the cam chamber (12) to the atmospheric pressure or above in the bypassed state. When the detection value of the viscosity of the lubricant output by the cam chamber sensor (12a) has become the predetermined allowable value or below, the three-way electromagnetic valve (62) is controlled to turn OFF so that the output side of the oil separator (13) communicates with the check valve (14) and the bypass route (61) is cut off.
