This thesis was dedicated to the design of a high bandwidth hot wire anemometer operating in constant temperature mode. To achieve this goal, the work was divided into several parts. Among them we can count: The development of differential equations that govern the operation of the anemometer based on the equations developed by Freymuth, the development of two Simulink and SimElectronics models, the experimentation of two electronic circuits with two different bandwidths and finally, the simulation of a stabilization technique of the control circuit.
To improve the bandwidth of the anemometer and by referring to the Freymuth’s hypothesis, we used a control loop consisting of two high bandwidth operational amplifiers. Simulation and testing of the electronic circuitry of the anemometer allowed us to conclude that increasing the bandwidth of the control loop requires consideration of several factors that can cause instability to the system.
