摘要
以交流转矩伺服系统简化模型为控制对象,设计了基于 H_∞鲁棒稳定控制器的两自由度内模控制器．仿真实验结果表明,在系统参数存在摄动的情况下,与传统控制器相比系统跟随性能、鲁棒稳定性均有所提高,有效抑制了参数摄动对系统性能的影响．
Taking the simple model of an alternating current torque servo system as the control object, a 2-degree of freedom inner model controller based on the H∞ robust controller is devised. Emulation experiments show that compared with a traditional controller both the traceability and robust stability of the new system are improved under variation of parameters, and the negative effect of the variation of parameters is limited.
