我们证明了对于约束有限时域线性模型预测控制,判定其全局渐近稳定性是不可判定的。这一结论在时域为一、状态、输入和终端权重为单位矩阵、优化器唯一且全局可行的情况下依然成立。分别通过约简覆盖了预测状态盒、硬输入盒和二次软化输入盒的情形。第四个约简将状态和输入维度固定为三维和六维。因此,不可判定性并非由长时域、维度增长、递推可行性失败或非唯一性所导致。
英文摘要
We prove that deciding global asymptotic stability for constrained finite-horizon linear model predictive control is undecidable. This holds at horizon one with identity state, input, and terminal weights, unique optimizers, and global feasibility. Separate reductions cover predicted-state boxes, hard input boxes, and quadratically softened input boxes. A fourth reduction fixes the state and input dimensions to three and six. Hence undecidability is not caused by long horizons, growing dimensions, failures of recursive feasibility, or nonuniqueness.
