摘要:

本文扩展了最近提出的一种算法,用于受过程和测量干扰的渐进稳定、线性时不变系统的模型辨识和鲁棒MPC。独立的输出预测为不同的步骤提前估计集成员的方法。它在这里示出,相应的预测误差界是最保守的所考虑的模型类。然后,一个新的多速率鲁棒MPC算法的开发,采用所述多步预测器鲁棒地强制约束和稳定性对干扰和模型的不确定性,并减少保守性。仿真实例验证了该方法的有效性。

英文摘要:

This note extends a recently proposed algorithm for model identification and robust MPC of asymptotically stable, linear time-invariant systems subject to process and measurement disturbances. Independent output predictors for different steps ahead are estimated with Set Membership methods. It is here shown that the corresponding prediction error bounds are the least conservative in the considered model class. Then, a new multi-rate robust MPC algorithm is developed, employing said multi-step predictors to robustly enforce constraints and stability against disturbances and model uncertainty, and to reduce conservativeness. A simulation example illustrates the effectiveness of the approach.
