In this study, a fan and plate apparatus is used to demonstrate the aerodynamic resonance phenomena and stability concepts. A series of controllers such as P, PD and PID are used to illustrate the aerodynamic behavior of this system. This laboratory apparatus can be used in an undergraduate or graduate controls course to illustrate and reinforce stability and controller design concepts. The xPC Rapid Prototyping Toolbox of MATLAB® is used for a fast and flexible method to implement a variety of controllers using a high-level programming language such as Simulink®.
