摘　　要：研究了完全抗干扰Smith预估控制方案的应用实现问题。用理论分析和仿真试验的方法证明了完全抗干扰Smith预估控制方案存在的可实现性问题和稳定性问题。其可实现性问题可以通过两环节串接后实现的方式避开,但是系统稳定性缺陷将导致整个方案的不可用。The application problem of a full anti-interference Smith predictor was studied.It was proved that there were the stability and realizability issues in the full anti-interference Smith predictor implementation by the theoretical analysis and simulation experiment.The realizability problem could be avoided by cascading two links,but the defect of system stability would cause the entire program unavailable.
