Description
Technical Field
The invention relates to the technical field of air conditioners, in particular to a PG motor control method, a PG motor control system and an air conditioner.
Background
The alternating current PG motor is a motor commonly used in an air conditioner, the rotating speed can be adjusted at will below the rated rotating speed through the voltage reduction and speed regulation of the controlled silicon, the rotating speed is very convenient to adjust, and the alternating current PG motor is particularly widely applied to a split wall-mounted indoor unit. The principle of motor speed regulation: the rotating shaft of the motor is provided with a magnetic ring, a fixed pulse number is output every time the motor runs, and the actual running rotating speed of the motor can be calculated by detecting the number of pulses in unit time; when the actual operation rotating speed of the motor is lower than the designed rotating speed, the control panel increases the rotating speed of the motor by increasing the output voltage of the controlled silicon until the target designed rotating speed is reached; similarly, when the actual operation rotating speed of the motor is higher than the design rotating speed, the control panel reduces the rotating speed of the motor by reducing the output voltage of the controllable silicon until the target design rotating speed is reached. Under normal conditions, the rotating speed of the motor can be adjusted at will within the range of the specified using rotating speed of the motor, and the rotating speed of the motor is very stable.
However, in the laboratory test of the air conditioner equipped with the alternating current PG motor, the condition that the rotating speed of the motor is unstable also exists, so that the test of the performance of the whole machine is influenced. The problem expression form is as follows: the rotating speed of the motor is unstable, and the rotating speed fluctuates in a large range (such as +/-100 r/min fluctuation), so that the air outlet volume of the air conditioner is large and small, and further, the performance indexes of the air conditioner such as refrigeration and heating are inaccurate to test. The reason for this problem is: when the air quantity is tested, the frequency of a variable frequency fan in the testing equipment is continuously adjusted, the load of the motor is continuously changed, the rotating speed of the motor is reduced when the load is increased, the rotating speed of the motor is reduced when the load is reduced, the rotating speed of the motor is increased when the load is reduced, the rotating speed of the motor is set to a target rotating speed, the output voltage of the controllable silicon is continuously adjusted by the electric control board, when the adjusting rate of the frequency of the variable frequency fan is consistent with the adjusting rate of the controllable silicon output voltage by the electric control board, the frequency of the variable frequency fan and the speed of the controllable silicon output voltage are continuously adjusted, the frequency of the variable frequency fan and the speed of the controllable silicon output voltage are always stable, and the motor can generate unstable rotating speed and fluctuate in a large range.

s200: when the air conditioner operates, the motor rotating speed of the corresponding wind speed gear is detected in real time;
s300: and judging whether the rotating speed of the motor is stable or not according to the actually detected rotating speed of the motor.
In step S300, specifically, determining whether the motor rotation speed is stable according to the actually detected motor rotation speed includes:

In addition, when the actually measured motor rotating speed is not in the preset range of stable rotating speed, the rotating speed of the motor is judged to be unstable, S500 is carried out to reduce the adjusting rate of the rotating speed of the motor, then S300 is carried out again to judge whether the rotating speed of the motor is stable, and if the actually measured rotating speed of the motor is in the preset range of stable rotating speed, the S400 air conditioner is carried out normally; and if the actually measured rotating speed of the motor is still not in the stable preset range, continuing to step S500 to reduce the adjusting rate of the rotating speed of the motor until the actual rotating speed of the motor is judged to be stable.
When the actual detection of the motor rotation speed in the step S300 is not within the preset range of stable rotation speed, the step S500 is performed to reduce the motor rotation speed and adjust the speed, and then the step S300 is performed again to determine whether the motor rotation speed is stable. The rate is adjusted by reducing the motor speed until the motor speed is judged to be stable.
Specifically, when the actually measured motor rotating speed is not within the preset range of stable rotating speed, the motor rotating speed is judged to be unstable, and the motor rotating speed adjusting rate is reduced, wherein the adjusting rate is reduced at a half rate for each adjusting rate.
