Control Law Design of Hypersonic Vehicle Based on Incremental Dynamic Inverse
The incremental dynamic inverse robust control law was designed for hypersonic reentry vehicle.Firsttwo loop control modelsfast and slowwere established for the hypersonic vehicle.The reentry foreign strong disturbance was estimated through nonlinear disturbance observer for feedforward compensation.Thenthe incremental dynamic inversion control laws were designed respectively for the fast and slow loop through the state rate feedback.Nonsmooth control lawwith high antiinterference ability and fast convergence speedwas used to improve the system robustness.Finallythe linear trackingdifferentiator was introduced to solve the problem that the state rate required by the incremental dynamic inversion control law cant be measured.The simulation verifies the effectiveness of the proposed algorithm.
