摘要
针对大量物理对象的高阶模型,将H∞控制中的模型匹配问题与高阶系统平衡截断降阶方法相结合,提出了鲁棒降阶控制方法。并将该方法应用于内模控制系统模型降阶,设计出低阶的内模控制器,使控制过程更为简洁,且易于实现。对设计的内模控制系统进行了仿真验证,仿真结果表明,该方法具有较好的适用性,能达到较好的预期效果。
In view of the high-order model of a large number of physical objects, robust reduction is proposed. It combines the H∞ model match problem and high-order model balance truncation reduction problem together. This method is applied to design the low-order system model in IMC which can make the control process simple and easy to realize. The simulation results show that the method has better applicability and can get the expected performance.
