摘要 以鲁棒控制不变集作为预测控制的终端约束集,设计了一种新的鲁棒预测控制算法.将预测控制在不同采样点的待优化控制律考虑为线性反馈控制律,并通过在线优化求解线性反馈增益.从理论上证明了若采用所设计的鲁棒预测控制器,则系统是输入状态稳定的.最后通过计算机仿真验证了所提出设计方法的可行性. Considering a robust control invariant set as the terminal constraint set of model predictive control(MPC),a robust MPC is designed.The controller to be optimized of MPC at different sampling time is considered as linear feedback controller.Then,the linear feedback gain is obtained through online optimization.The system is proved to be input-to-state stable by using this robust model predictive controller.Finally,computer simulation shows the feasibility of the proposed method.
