Description

The torque control device of compressor and method thereof
Technical field
The present invention relates to a kind of torque control device and method thereof of compressor, relate in particular to and consider that the extraneous gas temperature factor sets the driving voltage boundary value of motor and can carry out the torque control device and the controlling method thereof of the compressor of moment of torsion control.
Background technique
According to compression, the discharging operation of pump, the moment of torsion of compressor is along with angle of swing changes, and changes and causes vibration thereupon the rotating speed of rotor.
Rotating inertia force owing to rotor during high speed is bigger, thereby the variation of rotational speed is less, but the low speed situation below 30Hz is less owing to rotating inertia force, thereby the big more vibration of velocity variations also increases thereupon.
Therefore, measure a position probing time lag when every rotation 30 is spent and detect the revolution variation, and pass through to change the rotating force (moment of torsion) of the regulated quantity of motor driven voltage (PWM duty) with angle of swing adjusting rotor, thereby it is minimum with the inhibition vibration that revolution is changed.
That is, become big and interval that rotating speed diminishes at moment of torsion, by strengthening the driving voltage of regulated quantity increase motor; Diminish and the big interval of rotating speed change at moment of torsion, by reducing the driving voltage that regulated quantity reduces motor.
Because controlling object is whirling vibration, the rotation each time of rotor can be considered one-period, and the variation of the rotation of finishing in the very short time each time is more small, thereby utilizes certain data before once rotating that it is reflected to and carry out learning control in the present Electric Machine Control.Therefore, described adjusting is implemented to finish through about 30 seconds by learning control successively.
When controlling motor when connecting the rectangular wave control signal to inverter circuit, moment of torsion becomes ratio in current of electric, and speed becomes ratio in motor driven voltage.
Though, preferably come control torque by the control current of electric, but when employing utilizes the inverter circuit of rectangular wave control signal, owing to can not directly be controlled to than in the electric current of moment of torsion, and can only be controlled to than in the motor driven voltage of motor speed, even thereby motor driven voltage is identical, current of electric also might be different with load.
And, since moment of torsion finish compressed action, beginning discharging operation place reaches peak value, sharply reduce after this, and every rotation 30 degree of velocity variations detect once, this time resolving power that causes the torque peak place a little less than, thereby be difficult to follow the tracks of and detect.
Therefore, be to be difficult to the control current peak only, thereby need take to force to stop compressor operating, cause measures such as excess current to prevent that Peak current is too high in order to improve control efficiency by velocity variations.
As mentioned above, owing to can only and be subjected to the restriction of time resolving power according to the indirect control torque of motor driven voltage, more ideally control torque is unlikely from principle.
Therefore, can only reduce control efficiency slightly and be provided for limiting the boundary value (Limiter) of motor driven voltage amplitude of variation, make Electric Machine Control become stable.
Japan's publication " 2004-245215 number (torque control device and torque control method) " discloses the technology of utilizing described boundary value to carry out moment of torsion control.The method of this patent documentation control torque detects the discharge temperature (S11) of present compressor as shown in Figure 1; Parameters such as comparative result according to operating mode (freeze or heat), the operation frequency of compressor and compressor discharge temperature that is detected and targeted compression machine temperature are determined regulated quantity border value data (S12); Judge then whether whether operation frequency surpass 20 (S113) in variation and regulated quantity boundary value; Judged result if boundary value surpasses 20, then is set at 20 (S14) with this boundary value (TON LMT).Then, in order finally to prevent to set unsuitable value according to above-mentioned data boundary regulating method, externally store the moment of torsion upper control limits value of setting according to refrigerating operaton, heating operation, operation frequency in the storage (ROM) in advance, and regulating and controlling amount boundary value is no more than this value (S15).
But,, need consider a lot of parameters if will determine boundary value, and need test and establishment table or calculating formula under various conditions, thereby the new machine of every exploitation all needs a lot of time and efforts according to above-mentioned citing document.
In addition, as changing the once motor driven voltage of rotation according to circuit and its peak value of being used for detecting the current of electric peak value in another citing document Japan's publication " 2001-119981 number (driving-controlling device of compressor and air conditioner) ", and regulate reduction value.But,, thereby have the problem that increases cost of production because need be provided for detecting the circuit of current peak.
