摘　　要：运用多项式方程方法，设计一种多率自校正ＧＬＱＧ推理控制器。通过采用推理控制系统Ｉ／Ｏ 模型，把推理估计、ＬＱＧ 最优控制和自校正控制有机地结合起来，简化了推理控制系统的设计，实现了自校正控制。The inferential estimator and LQG optimal control are linked close together, basing on I/O model of inferential control system, by polynomial equation method. Thus the desigh of inferential cotnrol system is simplified and this inferential controller can be carried out by multirate self-tuning algorithm. This design method can also evaluate the robustness of inferential control system by sensitivity. And it is suitable for non-minimum-phase and unstable systems.
