System Identification and Controller Design of a Micro Air Vehicle using Magnetic Suspension and Balance System

摘要

Magnetic Suspension and Balance Systems (MSBSs) allow for non-contact balance and actuation. During wind tunnel tests, these systems can eliminate support interference to allow for more accurate measurements of aerodynamic forces and moments acting on an experimental model. MSBSs also make it easy to change the position and attitude of the model. Furthermore, MSBSs can adjust the Degree of Freedom (DOF) of the experimental model so that system identification and controller design can be effectively achieved during wind tunnel tests. In this paper, an MSBS is used during wind tunnel tests to measure the aerodynamic coefficients of a Micro Air Vehicle (MAV) model for various angles of attack and elevator deflection angles. The results are used to design a height hold controller for a MAV model. The height hold controller is implemented into the model and the MSBS is again employed during wind tunnel tests to measure the performance of the controller.
