VTOL Aircraft Optimal Gain Prediction via Parameterized Log-Sum-Exp Networks
2023 EUROPEAN CONTROL CONFERENCE, ECC(2023)
摘要
An optimal gain prediction method is proposed for VTOL aircraft controllers. The proposed method exploits parameterized convexity to quickly and reliably predict the optimal gain for a given initial state. The parameterized convexity is secured by using the parameterized log-sum-exp (PLSE) network, which is a shape-preserving universal approximator for parameterized convex continuous functions. A PLSE network is trained in the sense of supervised learning to approximate the cost function of initial state and gain. For a given initial state, the optimal gain is predicted by convex optimization. The result of numerical simulation demonstrates that the proposed method can perform real-time optimal gain prediction and outperforms compared to other network or adhoc approaches for the attitude and altitude control of VTOL aircraft.
