摘要
针对具有大负载高精度控制要求的气体能量控制阀瞬时启动的特点,确定了电液伺服驱动控制方案。建立元件及气体能量控制阀的系统模型,对各种控制曲线进行了仿真研究及试验研究。仿真研究充分揭示气体能量控制阀的性能特征,通过采取补偿措施,弥补了控制性能的不足。试验研究证明了仿真研究的正确性。
In this paper, according to instantaneouscharacteristics of jump--start, the control scheme forelectrohydraulic servo drive is determined under condi-tions of large load and high precision for control valve ofpneumatic restoring energy. And its element model andsystem model are set up. The simulation and experimen-tal resuts of manifold control curve are given. The perfor-mance of the valve is discoved by the simulation. Someinsufficiencies of the valve are compensated and experi-mental results testified that the simulation results areright.
