| Abstract: | 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. |

| Keywords: | Receding horizon control predictive control optimal control suboptimality continuous nonlinear system |
