迭代自适应控制在电液伺服系统上的应用

针对电液伺服力控系统的跟踪控制问题,提出一种迭代自适应的设计方案。通过融合迭代和自适应两种控制方式来设计控制器,综合两种控制方式的优点,解决由于系统的不确定性及干扰问题并保证系统的精确度,提高非线性不确定的复杂系统的控制性能。利用Matlab对方案的有效性进行了验证,仿真结果表明该方法能够使跟踪误差逐渐减小,较好的抵抗外界和内部的干扰,增强了系统的鲁棒性并提高了控制精度。

Application of Iterative Adaptive Control to Electro-hydraulic Servo System

For force tracking control of problem electro-hydraulic servo control system, an iterative adaptive control is designed, which introduce an adaptive iterative controller to resolve the uncertainty and exiting interference of system and to determine the iteration control parameters to ensure system ＇ s accuracy. Combining the advantages of two control methods, the performance of the non-linear, complex and uncertain control system improved. Using Matlab verify the effectiveness of program, simulation results show that the program can reduce the tracking error and do resistance to interference to enhance the robustness of the system and improve system control accuracy.
