Technical field
The present invention relates to machine control techniques field, in particular to a kind of compressor start method and device, storage medium.
Background technique
The start-up course of frequency-changeable compressor must be through after a period of time when not having built-in rotor position sensor
Opened loop control gives rotating speed of target in the case that is, no rotor phase information is fed back, and forces compressor operation.Then when full
Enough when certain setting condition, closed-loop control is cut from opened loop control.At this moment, because opened loop control does not have actual rotor phase to believe
Breath, so the actual phase of compressor drum and imaginary control phase exist centainly under different load pressure states
Deviation cuts closed-loop control, it may appear that torque is discontinuous, brings biggish mutation to revolving speed and phase current when deviation is larger
And impact, cause unstable system, cancel closedown, vibrating noise etc..
Currently in order to solving the above problems, there are mainly two types of schemes:
A kind of scheme is to increase rotor-position sensor inside compressor, and actual rotor phase information is fed back to control
Unit processed, control unit are directly adjusted according to feedback information, ensure that the actual motion under the conditions of different loads and control
It is consistent.But the cost increase of compressor can be made by increasing position sensor, and sensor is component easy to damage, in compressor
Under conditions of portion is relatively severe, the reliability of product is greatly reduced；
Another scheme is to increase the starting time of compressor, waits the actual phase and imaginary control of compressor drum
After deviation between phase drops to reasonable range, then incision closed loop is carried out, to effectively slow down switching bring impact.
But this method only passively waits, and extends the time of opened loop control, since the running current of opened loop control is larger, when long
Between operation will increase the temperature rise and thermal losses of compressor, influence efficiency.In addition, waiting time needs real-time monitoring phase inclined
Difference increases the operand of control unit.

Electric current I2.
The current value of I2 needs to guarantee that the deviation between the actual rotor phase of compressor and imaginary control phase is realized
Adjust automatically.
Wherein, adjust automatically are as follows:
When the advanced imagination control phase of actual rotor phase, given direct-axis current I1 and quadrature axis current I2 carry out vector
Superposition reduces the torque current component of actual rotor to reduce output torque, so that imagination control phase is gradually close to practical
Rotor phase reduces phase deviation, until being 0；
When actual rotor delayed phase imagination controls phase, given direct-axis current I1 and quadrature axis current I2 carry out vector
Superposition increases the torque current component of actual rotor to increase output torque, so that actual rotor phase is gradually close to imagination
Phase is controlled, phase deviation is reduced, until being 0；
When actual rotor phase is equal to imagination control phase, given direct-axis current I1 and quadrature axis current I2 carry out vector
Superposition, maintains the torque current component of currently practical rotor, phase deviation remains 0 at this time.
In order to which the deviation between the actual rotor phase of compressor and imaginary control phase realizes adjust automatically, the electricity of I2
Flow valuve can be set based on above-mentioned table 1.
