Title: Device for controlling power factor of synchronous motor
Inventor: FUJII YOSHIAKI
IPC: H02P25/10
Filed: 1993-05-24
Abstract: PURPOSE:To make it possible to prevent the overshoot in power factor control due to the delay of exciting current control from fluctuating according to the magnitude of a synchronous motor load in controlling the power factor of the synchronous motor. CONSTITUTION:A first adder 9 calculates the deviation of a power factor command value set at a power factor setter 8 from the power factor detected at a power factor detector 7. The result of the calculation is corrected in a power factor control/correction circuit. The power factor control/correction circuit varies the amount of correction according to the current through a synchronous motor 2 detected at a motor current detector 21, and feeds the result of the correction to a comparator type power factor control device 10. The power factor control/correction circuit 22 consists of, for example, a function generator 23 that outputs the amount of correction corresponding to the current detected by the motor current detector 21; and a fourth adder 24 that adds the amount of correction output from the function generator 23 to the deviation calculated by the first adder 9.

Title: Temperature controller of heavy oil heater
Inventor: KOMENO KAZUO
IPC: G05D23/19
Filed: 1984-06-14
Abstract: PURPOSE:To secure a wide control range without deteriorating the controllability by applying the control of temperature that controls only a range of low heat exchange quantity where the controllability is deteriorated according to the increase or decrease of the heat transmission area. CONSTITUTION:When the output of a deviation controller 2 is set lower than a certain level to the opening amount of a steam flow rate control valve 4, the output of a function generator 7 is outputted by changing the level set value by an amount larger than the reference water level 10. Thus a difference is produced between the output of a condensed level oscillator 6 and that of a function generator 7, and the output of a deviation controller 8 delivers a closed signal to a condensed water level control valve 9. The level 10 is raised up for condensed water by closing the valve 9, and the control of temperature is carried out within a range of low heat exchange quantity with reduction of a heat transmission area. Thus a wide control range of temperatures is secured without deteriorating the controllability.
