Robust Stability Conditions for DMC Algorithm of Constrained Delay Uncertain System
时滞不确定系统DMC约束控制的鲁棒性条件

Sufficient and necessary conditions for delay linear uncertainsystems(DLUS) with constrained control variable are discussed in this paper.There are two contributions:first,the new DMC control algorithm is given,in which compensations ε1(k) for model error and ε2(k) for disturbance are introduced to decrease predictive error;second,the sufficient and necessary conditions for robust stability of the closed loop system are given and the relations between model error,disturbance,predictive error and expected output that assure robust stability of the system are investigated.
