摘要
该文在考虑摩擦和负载对系统影响的基础上,建立了比例阀控气动伺服系统的待辨识模型,并根据进一步工作的需要对模型进行了合理简化。采用递推的最小二乘法,得到符合控制要求的简化系统模型,同时给出辨识过程的详细步骤。理论分析和实验数据的验证表明了辨识的有效性。
Candidate model of proportional valve controlled pneumatic servo system was selected and simplified to meet the need of practical application, under the influence of friction and load. The recursive least-squares algorithm was used to obtain the simplified system model. The result of system identification is proved both through theoretical analysis and experimental data.
