Abstract

Growing demand for robust, low-computation sensing and control of micro-air vehicles motivates development of new technology. A MEMS wind flow sensor was previously developed at the University of Maryland, drawing inspiration from setae structures seen in biology. In this work this sensor is integrated onto a quadrotor platform and utilized for sensing a gust perturbation. Suitable signal processing methods were used to isolate the gust-related perturbation from other ambient fluctuations affecting the sensor. The problem of gust rejection is then formulated using standard tools from robust control theory and a controller is obtained using μ–synthesis. Theoretical analysis of the μ controller’s performance improvement is carried out with simulations. A robustly stable controller was implemented on a quadrotor micro-air vehicle to improve lateral state regulation in the presence of a lateral gust stream. Flight testing revealed attenuation of the lateral velocity and perturbation from the projected path.
