摘要:

为提高异构双阀电液伺服系统的控制性能,在融合强化学习与自适应鲁棒控制算法的异构双阀协调控制策略SAC-ARC的基础上,开展SAC-ARC控制策略仿真分析及实验验证。首先利用AMESim和Simulink软件平台建立了液压系统联合仿真模型,分析了不同比例阀控制信号补偿策略下异构双阀电液伺服系统的跟踪性能。然后对比仿真了SAC-ARC与PID、ARC及RBF-ARC控制策略在多种复合信号及系统受到内外扰动等复杂工况下的跟踪误差,以验证其跟踪性能与鲁棒性。最后在搭建的实验平台上进行了实验验证。仿真与实验结果表明:SAC-ARC控制策略在各工况下均表现出优异的跟踪性能,其最大瞬态误差和累计跟踪误差均显著低于其他对比控制策略,验证了该控制策略在异构双阀电液伺服系统中的有效性与优越性。

Abstract:

To enhance the control performance of a dual-valve electro-hydraulic servo system,this study conducts simulation analysis and experimental validation on a proposed coordinated control strategy, SAC-ARC, which integrates reinforcement learning with adaptive robust control.First, a co-simulation model of the hydraulic system was established using the AMESim and Simulink software platforms, and the tracking performance of the dual-valve electro-hydraulic servo system was analyzed under various proportional valve control signal compensation strategies. Subsequently, comparative simulations were performed to evaluate the tracking performance and robustness of the SAC-ARC strategy. The tracking errors of SAC-ARC were compared with those of PID, ARC, and RBF-ARC control strategies under complex working conditions, including various composite signals and the presence of internal and external disturbances. Finally, experimental validation was carried out on an established test platform. The simulation and experimental results demonstrate that the SAC-ARC control strategy exhibits superior tracking performance under all tested working conditions. Its maximum transient error and cumulative tracking error are both significantly lower than those of the comparative control strategies, thus validating the effectiveness and superiority of the proposed strategy for the dual-valve electro-hydraulic servo system.

Key words: electrohydraulic servo system, dual-valve parallel control, flow allocation, co-simulation
