Abstract

This paper proposes a new architecture of a controlled-temperature hot-wire anemometer using voltage feedback linearization. The voltage feedback linearizes the sensor input-output relationship and the controller is designed to achieve null steady-state error and reduce the system response time. Analysis of the behavior of the architecture modeled using Simulink is presented for a NTC sensor. Simulation results are presented and discussed, and the architecture is compared with the classical constant-temperature anemometer (CTA) one.
