Abstract
Systems and methods for providing constant airflow based on direct motor power control and advanced motor system modeling are described. A power and speed of a motor may be determined based on static pressure in the system. A target airflow rate for the system may be obtained, and a target motor power that yields the target airflow rate in the system may be determined based on the determined speed of the motor and the obtained target airflow rate for the system. A determination of whether the determined motor power is approximately equal to the target motor power may be made, and the power of the motor may be adjusted when the motor power is not approximately equal to the target motor power.
