Abstract: An air compressor comprising: a tank (50), a compression mechanism (30), a motor (5) and a control circuit (7). The control circuit (7) includes a CPU (70) and a storing unit (74) which stores a control program, the compressor operation history and a plurality of operation modes. Each of the operation modes is defined by two setting values: a reference restart pressure value and a motor rotational speed value, at least one of these values being different from among the plurality of modes. The control circuit (7) executes one of the plurality of modes as a target mode in which the control unit controls the motor to restart by comparing the pressure in the tank with the reference restart pressure and rotates the motor at the rotational speed of the target mode. The control circuit changes the target mode from the one of the plurality of modes to another one of the plurality of modes based on the compressor operation history.

Abstract: The presence or absence of boost pressure is determined from an error between F-P characteristics showing the relationship between the output frequency of an inverter and the power consumption and an actual operating point. When there is boost pressure, an amount of correction of linearized characteristics showing the relationship between quantity and discharge side pressure is automatically calculated based on the error, and the linearized characteristics are corrected. Subsequently, by carrying out a PID control in accordance with a target pressure obtained from post-correction linearized characteristics, the output frequency of an inverter unit is controlled, and an estimated constant end pressure control is carried out. Because of this, a pressure sensor or quantity sensor on a pump intake side is rendered unnecessary, and a simplification and reduction in cost of a feed water pump control device are possible.

Abstract translation: 增压压力的存在或不存在根据表示逆变器的输出频率与功耗之间的关系的F-P特性与实际工作点之间的误差来确定。 当存在增压压力时，基于该误差自动计算出显示出量侧压力与排出侧压力之间关系的线性化特性的校正量，校正线性化特性。 随后，通过根据从校正后线性特性获得的目标压力执行PID控制，控制逆变器单元的输出频率，并且执行估计的恒定端压力控制。 因此，不需要在进气侧的压力传感器或量传感器，并且能够简化和降低给水泵控制装置的成本。
