提出了一种基于状态观测器的约束后退视界输出反馈控制方法。该方法采用由“可行不变集”和“自由控制动作”组成的后退视界双模范式。导出了状态估计的多面体可行不变集，并给出了状态估计误差的保证界。通过考虑包含可能的初始估计误差的状态估计误差的不变集，建立了状态估计误差的保证界。对未来状态的预测是基于估计的当前状态和当前估计误差的界限。确定自由控制动作，使预测的未来状态属于多面体可行不变集，不受输入约束和测量噪声的影响。
In this paper, a constrained receding horizon output feedback control method which is based on a state observer is suggested. The proposed method adopts the receding horizon dual-mode paradigm which consists of a 'feasible invariant set' and 'free control moves'. Polyhedral feasible invariant sets of estimated state are derived along with guaranteed bounds on state estimation errors. The guaranteed bounds on the state estimation error are developed by considering invariant sets of state estimation errors which include possible initial estimation errors. Predictions of future states are made based on estimated current state and bounds on current estimation error. The free control moves are determined so that the predicted future state belongs to the polyhedral feasible invariant set, despite input constraints and measurement noise.
