| 摘 要： | 针对实际工业过程中多变量系统存在着非线性、工况范围广、耦合强的特点,提出基于设定值观测器的非线性多模型广义预测解耦控制算法。该方法由线性广义预测控制器、一种新的设定值观测器和切换机构组成。理论分析和仿真结果表明,该控制策略不但可以保证闭环系统B IBO稳定和渐近收敛,而且能够得到很好的控制效果。

| Abstract: | According to the characteristics of multi-input multi-output（MIMO）,nonlinear and large operating range in the systems of real industrial processes,a new multi-model generalized predictive decoupling（GPC） control algorithm was presented.It was composed of a linear generalized predictive controller,a new reference observer and a switching mechanism.Theoretical analysis and simulation results show that the closed-loop stability and asymptotical convergence of tracking error can be guaranteed,and the control results are improved. |
