Angular-Accelerometer-Based Flexible-State Estimation and Tracking Controller Design for Hypersonic Flight Vehicle

The controller design of hypersonic flight vehicles is a challenging task, especially when its flexible states are immeasurable. Unfortunately, the difficult to measure directly. In this paper, an angular-accelerometer-based method for estimation proposed. By adding pitch angel angular accelerometer and designing Extended Kalman Filter-based online method, could be obtained in real time. Then, based on estimated states, stable inversion-based controller-design was utilized, robust tracking designed vehicles. proposed provides effective means estimating conducting observer-based Finally, numeral simulation given show effectiveness control method.
