本文针对液压伺服系统的特点，运用Ｈ∞控制理论，提出了一种控制器，它能在保证系统鲁棒稳定性的同时确保系统的瞬态性能指标，并把此控制器运用到泵控马达系统中，仿真结果表明了它的有效性。
Aiming at the characteristics of hydraulic servo system and using H∞ control theory, a controller is proposed to ensure the robust performance of the system while ensuring the transient performance of the system. The controller is applied to a pump-controlled motor In the system, the simulation result shows its validity.
