摘要
针对一般连续非线性系统，研究了有终端约束的稳定预测控制策略相对传统最优控制的次优性问题．通过分析预测控制的有限时域滚动优化性质，得到了预测控制次优性的上界，并且将该结果应用于连续线性系统，得到了一个量化的次优性评价指标．
Considering the general continuous nonlinear systems,the suboptimality of stable predictive control with terminal constraints is studied and compared with the traditional optimal control.By analyzing the property of receding finite\|horizon optimization,the upper bound of suboptimality is obtained.The result is applied to linear systems,and a suboptimality quantized index is proposed.
