摘　　要：基于Simulink仿真平台,给出适合应用于液压系统的自适应控制策略。为简化控制算法,在设计自适应控制器时,只考虑控制输入作用,忽略随机干扰的作用,从而极大地简化了自适应控制器,有利于在线实时控制。通过大量的仿真研究,说明用这种简化的控制策略能有效地控制包含随机干扰作用下的整个液压控制系统,它不仅能使一个不稳定的系统变为稳定,且能在随机干扰作用下,也能渐近一致地跟随参考模型的希望输出,使被控系统满足性能指标要求。Based on Simulink simulation platform, suitable self-adaptive control method applied in hydraulic system was given. To simplify control algorithm, only the action of control input was considered and the action of random disturbance was not taken into account when self-adaptive controller was designed. Therefore, self-adaptive control was simplified and favorable to do real-time control online. According to the simulation research, it is shown that the simplified control method can control the whole hydraulic control system including the action of random disturbance , it can convert unstable system into stable system, and can gradually and consistently follow the expected output of reference model to make controlled system to be content with the requirements of performance index under the action of random disturbance.
