四、报告题目：Self-Triggered Adaptive Model Predictive Control for Constrained Nonlinear Systems （自适应模型预测控制）

报告摘要：

      Model predictive control (MPC) is a promising paradigm for high-performance and cost-effective control of complex dynamic systems. Yet, the MPC schemes and the corresponding optimization problem closely rely on the model of the dynamic system under consideration. In real applications, the mathematical model is hard to be precisely known or even varying.  This talk will introduce a self-triggered adaptive model predictive control (MPC) method for constrained discrete-time nonlinear systems subject to parametric uncertainties and additive disturbances. Firstly, a real-time zonotope-based set-membership parameter estimator is developed to refine a set-valued description of the time-varying parametric uncertainty based on the available measurements. We leverage this estimation scheme to design a novel self-triggered adaptive MPC (ST-AMPC) approach for uncertain nonlinear systems. Compared with the existing self-triggered robust MPC methods, the proposed ST-AMPC method can further reduce the average sampling frequency while preserving comparable closed-loop performance. Then, we theoretically show that, under some reasonable assumptions, the proposed ST-AMPC algorithm is recursively feasible, and the closed-loop system is input-to-state practical stable (ISpS) at triggering time instants. Finally, some existing challenges and future research directions will be discussed.
