Filed: 1997-11-13
Abstract: PROBLEM TO BE SOLVED: To restore the deviation early when the real number of revolutions exceeds the prescribed value of the set number of revolutions while suppressing overshoot, by realizing high precision control even if the time interval to detect the deviation of the real number of revolutions to the set number of revolutions is long. SOLUTION: In this heat pump system, the engine to drive a compressor is controlled in the number of revolutions by an electronic governor system. CPU in the electronic governor system calculates command value SPID by a calculation formula of PID control based on the real number of revolutions Nr obtained from an ignition pulse signal and the set number of revolutions and controls the driving of a step motor to determine throttle opening. Two threshold values A1 and A2 are set on a low speed side of the number of idling revolutions, which is a lower limit value of the set number of revolutions, and a waveform pattern P2 to be expressed by a function SD2 in A2<=Nr<A1 is added and a waveform pattern P1 to be expressed by a function SD1 in Nr<A2 is added to correct the command value SPID.

The revolutions are converted to frequencies. When the frequencies approach the natural frequencies, a signal for improving bearing rigidity is fed to a bearing pressure mechanism 5 so as to pass a resonance point. At this time, a bearing spring constant estimating means 6 feeds back a constant calculated by pressing force to the analyzing means 3. Therefore, the difference between the actual natural frequencies and the frequencies at that time can be obtained by the input calculating means 4, and suitable control can be performed.  Therefore, low vibration and low noise can be achieved.
