摘要
自行火炮输弹机提升机构将放置在炮车底部的弹丸提升到炮膛高度。针对该系统对运行稳定性的要求以及在运动过程中,系统参数和外干扰会发生变化的特点,设计H∞鲁棒控制器,利用μ综合分析验证加入控制器后系统鲁棒性。仿真和实验表明:加入H∞控制器系统对参数变化和负载变化有很强的鲁棒性,并显著改善了系统对输入信号的跟踪性能。
Hydraulic lift device of ram mechanism of self-propelled gun is used to lift projectile from the bottom of gun bogle to its launching height. Aimed at this system required of good stability performance with its characteristics of parameters and interference force varying through the whole movement process,the H∞robustness controller was designed. The robustness of system was verified after the controller added by using a μ-synthesis analysis. Simulation and experimental results show that a H∞controller added system is highly robust against variations in parameters and loading,and effectively improves tracking performance to input signals.
