摘要： A high pressure container system is equipped with an upstream side pressure sensor that measures an internal pressure of high pressure containers upstream of a pressure regulating valve, a plurality of downstream side pressure sensors that measure the pressure of the fluid downstream of the pressure regulating valve, and a control device. At a normal time of the downstream side pressure sensors, a control device monitors the internal pressure of the high pressure containers on the basis of the measured values of the downstream side pressure sensors, and at an abnormal time when any one of the downstream side pressure sensors is abnormal, the control device monitors the internal pressure of the high pressure containers on the basis of the measured values of the downstream side pressure sensors, and the measured value of the upstream side pressure sensor.

摘要： A motor driving control method for controlling a motor speed so that a speed measured value of a motor follows a speed command value is provided. The method includes driving the motor by repeating an on section where a torque is generated in the motor and an off section where a torque is not generated in the motor at a regular period, based on the speed command value, wherein the driving includes applying a phase voltage to only one of multiple phases of the motor in the on section by a pulse width modulation scheme.
