摘　　要：为方便液压自适应控制系统的研究,根据误差方程多项式代数法自适应控制理论,提出了基于S imu lin ik图型模态,构成了液压自适应控制系统。这种自适应控制方法与其他控制方法相比,具有控制精度高,控制器结构简单,自适应能力与实用性强等特点。文中详细讨论了自适应控制系统的构成及基于S imu lin ik图型模态液压自适应控制系统的实现问题,通过大量仿真研究,说明这种构成方法是正确的,所采用的自适应控制策略,具有很强的自适应控制能力,控制精度高,它不仅能使不稳定的系统变为稳定,且能渐近一致地收敛于希望模型的输出,使系统满足其动态性能的要求。Figure mode based on Simulink is presented to construct the hydraulic serf - adaptive control system in this paper for studying the hydraulic self - adaptive control system more conveniently. Compared with other control methods, the adaptive control method has the characteristic of high control accuracy and simple controller＇ structure and better adaptability. The construction of self - adaptive control system and the realization of self - adaptive control system based on Simulink figure mode are particularly discussed in this paper. The results of simulation experiments show that this constrcting method is correct and the self - adaptive control system has good adaptive control ability and high accuracy. It can not only make the unsteady system to be steady but also can make the output follow the output of the reference model progressively. The dynamic performance of the system can be satisfactory in this way.
