模型参考和重复控制在电液伺服协调加载系统中的应用研究

摘要

The control strategy of model reference control and repetitive control in combination was proposed. It was applied to the multi-channel electric hydraulic harmonized synchron-force servo loading system. The control ability of the system was demonstrated , and the computer realization for algorithm was given. The simulation results show that the system self-adaptive ability is improved by this control strategy, and the following up synchronous precision and robustness are improved, which is used as reference for synchronous control of common uncertain system.%提出一种由模型参考和重复控制相结合的控制策略,并将其应用于多通道电液力协调加载系统中,论证了系统的可控性,并给出算法的计算机实现.仿真结果表明:该控制策略增强了系统的自适应能力,提高了同步跟随精度和鲁棒性,对一般不确定系统的同步控制具有借鉴作用.
