摘要
将非线性补偿和 PI控制策略相结合 ,针对棒材连轧机立式活套系统提出了一种多变量自适应解耦控制器 ,从理论上证明了闭环系统大范围渐近稳定 ,自适应参数能以很小的误差跟踪实际参数的变化 ,并给出了可用于控制器参数整定的系统动态性能与控制器参数间的定量关系 .
A multivariable adaptive decoupling controller by combining nonlinear compensation with PI strategy is proposed for the vertical loop of continuous bar mill. It's mathematically proved that the close loop system is globally asymptotically stable and the adaptive parameters can track the real values with small error. The relationship between the controller parameters and the dynamic performance of close loop system, which can be used to tune the controller parameters, is given by some formula. Computer simulation and industrial experimentation show that the controller has good performance.
