ABSTRACT:
An adaptive airflow control system for positioning damper systems or controlling air units utilized in an environment control system is provided. The system is based on a fixed-gain, proportional-only feedback design to provide stable operation given the nonlinear behavior of flow through a valve or damper. A time-dependent deadzone of nonlinearity is used to reject measurement noise. The deadzone of nonlinearity is adjusted by an adaptively calculated proportionality constant which is capable of switching the control system between various operating modes for adjusting the performance of the system.
