Washing machine appliance

A washing machine appliance, comprising:

• a cabinet;
• a tub positioned within the cabinet;
• a drum rotatably mounted within the tub, the drum defining a wash chamber for receipt of articles for washing;
• a motor in mechanical communication with the drum, the motor configured for selectively rotating the drum within the tub;
• and
• a controller in operative communication with the motor and configured to perform operations, the operations comprising:
• operating the motor to rotate the drum for a first time period, wherein a target motor speed is ramped from a first speed to a second speed during the first time period;
• determining an average deviation of an actual speed of the motor from the target motor speed over the first time period;
• comparing the average deviation to a first threshold value;
• determining an average power consumption of the motor over the first time period;
• comparing the average power consumption to a second threshold value;
• and
• performing a rebalancing process when both the average deviation is greater than the first threshold value and the average power consumption is greater than the second threshold value.
