摘要 提出了一种采用带智能前馈补偿器（IFFC）的复合控制器的电液被动力跟踪系统的控制方案，该方案被设计为在某种平原上重现反推力系统地面空气动力载荷的测试设备。通过详细分析，建立了数学模型和仿真模型。针对传统比例积分（PI）方法对参数不确定性的适应性较差的问题，提出了一种具有离线自整定机制的IFFC。进行了相关仿真，结果表明，即使PI部分的参数不是最优的，训练后的复合控制器仍具有良好的性能。为了验证所提出的控制策略的可行性，在电液测试平台上进行了实验，实验结果证明了所提出的带有IFFC的控制器对于不同跟踪任务的有效性。
Abstract This article presents a scheme for the control of an electro-hydraulic passive force tracking system using the compound controller with an intelligent feed forward compensator (IFFC), which is designed as a test equipment to reproduce on-ground aerodynamics load for reverse thrust system on a certain kind of plain. Through detailed analysis, the mathematical and simulation models are established. Since the conventional proportion integration (PI) method is unsatisfactory due to its bad adaptability to the parametric uncertainties, an IFFC with an off-line self-tuning mechanism is proposed. The related simulations are made and the results show that the compound controller will have good performance after training even though the parameters of the PI part are not optimal. To validate the feasibility of the proposed control strategy, the experiments are carried out on an electro-hydraulic test platform and the experimental results demonstrate the effectiveness of the proposed controller with IFFC for different tracking tasks.
