摘要
针对阀控非对称缸电液伺服系统存在的缺点,提出以对称缸为参考模型,利用基于误差方程的模型参考自适应控制原理设计自适应控制器,并利用SIMULINK对系统仿真。结果表明,经过模型参考的自适应控制系统能克服原有缺点,动态性能得到很大改善。
In consideration of the shortcomings of valve controlled asymmetrical cylinder electro-hydraulic servo system, this paper put forward symmetric cylinder as reference model, and designed adaptive controller based on the error equations model reference adaptive control principle. SIMULINK was used for system simulation. The results indicated that the model reference adaptive control system overcame the shortcoming and the dynamic performance of the original were improved greatly.
