Dynamic Event-Triggered Lyapunov-Based Model Predictive Control for AHV Under Disturbance and Multiple Constraints

External disturbances in complex environments often have a serious impact on the control system performance. For the tracking control problem of an air-breathing hypersonic vehicle (AHV) longitudinal attitude system with unknown disturbances and multiple constraints, a dynamic event-triggered Lyapunov-based model predictive control (DET-LMPC) based on disturbance preview (DP) and control barrier function (CBF) scheme is proposed. To obtain the future disturbance information, DP is introduced to estimate the current and the future disturbances’ values, and used as the basis for designing predictive control technique. Then, a Lyapunov convergence constraint (LCC) imposed on the entire prediction horizon is given based on DP to ensure the stability of the closed-loop system. Moreover, to ensure that the AHV flies safely under disturbances, a dynamic predictive constraint for angle of attack is provided and realized by CBF added to the cost function. Furthermore, a dynamic event-triggered mechanism based on DP and LCC is taken into account to alleviate the calculation burden and maintain the anticipated tracking performance, simultaneously. The sufficient conditions ensuring the feasibility of the presented algorithm and the stability of the closed-loop system are analyzed. Finally, the simulation study demonstrates the effectiveness of the proposed DET-LMPC with DP and CBF scheme.
