摘要: This talk will report a recent work on integral-type event-triggered model predictive control (MPC) of continuous-time nonlinear systems. In this work, an integral-type event-triggered mechanism is proposed by incorporating the integral of the error between the actual and predicted state, leading to reduced average sampling frequency. Besides, a new and less conservative robustness constraint is introduced to handle the additive disturbance, rendering the MPC problem with a relatively larger initial feasible region. Furthermore, the feasibility of the integral-type event-triggered MPC scheme and the stability of the closed-loop system are rigorously investigated. Sufficient conditions for guaranteeing both of these properties are established, showing that the recursive feasibility and stability depend on the prediction horizon, the disturbance bound, the triggering level, and the contraction rate for the robustness constraint. Simulation and comparison studies demonstrate the effectiveness of the proposed scheme. 简历: Yang SHI received the Ph.D. degree in electrical and computer engineering from the University of Alberta, Edmonton, AB, Canada, in 2005.
