Fixed-Time Controller Design for Aero-Engines: A Switched System Approach

Résumé

In the aero-engine control, fast response capability is significant in transient performance, especially when aircraft work in emergency scenarios. To improve the response speed of aero-engines, this brief proposes a type of fixed-time control using the switched system approach. First, aero-engines are modeled as switched systems to better reflect the multimode characteristics under various operating tasks. Then, the fixed-time controller is proposed, which has advantages of small computation and easy implementation. Novel criteria are proposed for fixed-time stability analysis of the closed-loop system under restricted switchings. Furthermore, specific calculations are provided to derive the upper bound for the convergence time. Finally, superiorities of the proposed method are validated through experimental results.
