基于T-S模型的旋转式起重机稳钩保性能控制

摘要

Cost guaranteed controller based on T-S model is robust for the control of a uncertain nonlinear system such as the contajner crane anti-swing system. The system stability and cost guaranteed control are transformed into solution of LMls. An optimal feedback matrix is obtained with the method. A cost guaranteed controller based on T-S model was designed and simulated. The result indicate that this method is simple, feasible and robust.%基于T-S模型的保性能控制对控制带有不确定性系统(如旋转式起重机稳钩系统)有很好的鲁棒性,把系统可稳和保性能控制转化为解一系列矩阵不等式(LMl)的问题,得出最优的反馈矩阵,设计出基于T-S模型的最优保性能控制器,并对这种方法进行了仿真.结果表明,这种方法简单可行,并且具有很好的鲁棒性.
