本文提出了一种新的多输入多输出电液伺服系统解耦自适应控制方案,它是广义最小方差自校正控制和参考模型自适应控制相结合的控制方案,能保证良好的动态解耦性能、高跟踪精度和适当的控制信号值.稳定性分析表明:本方案既适用于最小相位系统,也适用于非最小相位系统.使用本方案对一个两输入两输出的电液伺服系统进行了数字仿真和实时控制,取得了很大的成功.控制算法十分简捷,因而它适用于快动态系统.
This paper presents a new multi-input multi-output electro-hydraulic servo system decoupling adaptive control scheme, which is a combination of generalized minimum variance self-tuning control and reference model adaptive control scheme to ensure good dynamic decoupling performance , High tracking accuracy and the appropriate control signal value.Stability analysis shows that: This scheme is suitable for both minimum phase system and non-minimum phase system.Using this scheme, a two-input and two-output electro-hydraulic servo system was digitized Simulation and real-time control, has achieved great success.Control algorithm is very simple, so it is suitable for fast dynamic systems.
