H∞ robust controller used in an alternating current torque servo system

摘要: 以交流轉矩伺服系統簡化模型為控制對象,設計了基于H∞魯棒穩定控制器的兩自由度內模控制器．仿真實驗結果表明,在系統參數存在攝動的情況下,與傳統控制器相比系統跟隨性能、魯棒穩定性均有所提高,有效抑制了參數攝動對系統性能的影響．Abstract: 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.
