基于H_∞控制的火炮电液伺服系统研究

The Design of the Electro-hydraulic Servo System in the Artillery Based on H_∞ Control

针对某火炮电液伺服系统存在数学模型的不确定性和较大干扰力矩的特点 ,用H∞ 控制方法设计了两自由度控制器 ,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 ,仿真结果表明该方法对参数不确定性和外部干扰力矩具有很强的鲁棒性。

Focused on the model uncertainties and torque disturbance of the electro hydraulic servo system in the artillery,this paper proposes a two degree controller based on H ∞ control theory,which can guarantee the robustness and dynamic performances of the system.The simulation results demonstrate the controller robust to parameter uncertainties and disturbance torque.
