本文在分析已有的自适应算法和Clarke等人提出的广义预测控制算法的基础上，研究了具有变大阶和变滞后的非最小相位对象的控制问题，涉及的过程为全熔透钨极气体保护焊。被选为主要的控制策略。构造了一种自适应广义预测解耦控制方案。针对非最小相位多变量对象的解耦问题，提出了一种预测解耦算法。执行仿真以确定算法的默认参数。通过仿真和实验验证了该算法的性能。
This application paper addresses the control of a nonminimum-phase plant with variable large orders and delays, The process concerned is full penetration gas tungsten are welding, Based on an analysis of accepted adaptive algorithms, the generalized predictive control algorithm presented by Clarke et al. is selected as the principal control strategy. An adaptive generalized predictive decoupling control scheme is constructed. To decouple our nonminimum-phase multivariable plant, a predictive decoupling algorithm is also proposed. Simulations are performed to determine the default parameters of the algorithms. The performance has been tested by both simulations and experiments.
