针对传统动态逆鲁棒性差的特点，设计了基于增量动态逆的高超声速飞行器的再入鲁棒控制律。首先建立了高超声速飞行器快慢两个回路的控制模型，通过非线性干扰观测器估计再入动力学外来的强干扰，进行前馈补偿；然后通过状态速率反馈，对快慢回路分别设计了增量动态逆控制律，期望动力学采用了抗干扰能力和收敛速度快的非光滑控制律，提高了系统的鲁棒性；引入了线性跟踪－微分器解决了增量动态逆控制律所需状态速率无法测量的问题。最后，通过仿真验证了所提算法的有效性。

The incremental dynamic inverse robust control law was designed for hypersonic reentry vehicle.Firsttwo loop control modelsfast and slowwere established for the hypersonic vehicle.The reentry foreign strong disturbance was estimated through nonlinear disturbance observer for feedforward compensation.Thenthe incremental dynamic inversion control laws were designed respectively for the fast and slow loop through the state rate feedback.Nonsmooth control lawwith high antiinterference ability and fast convergence speedwas used to improve the system robustness.Finallythe linear trackingdifferentiator was introduced to solve the problem that the state rate required by the incremental dynamic inversion control law cant be measured.The simulation verifies the effectiveness of the proposed algorithm.
