【摘要】：伺服系统作为机电一体化系统中关键执行部件,其控制器刚度设置需要随负载惯量、轴系刚度等外部机械参数改变而作相应整定,因此外部机械参数辨识具有重要意义。单惯量刚性系统以转动惯量为主的参数辨识方法已经在近20年大量涌现,成熟度较高。但实际系统的传动机构多为弹性部件,会引发系统的机械谐振,进而导致系统性能恶化,因此双惯量弹性系统的参数辨识实际意义更为重大,并逐渐成为热点研究方向。双惯量弹性系统的参数辨识可分为等效单惯量辨识法、参数法和非参数法3种方法。该文分析双惯量弹性系统每种辨识方法的基本思想,对比各自优缺点,剖析辨识算法在各工业领域中的应用,总结现有研究成果及有待解决的问题,并展望未来的研究方向。
[Abstract]:Servo system as a key executive component in the mechatronics system, its controller stiffness setting needs to be adjusted according to the load inertia, shaft stiffness and other external mechanical parameters. Therefore, the external mechanical parameter identification is of great significance. The single inertia rigid system based on the moment of inertia parameter identification methods have emerged in large numbers in the last 20 years. However, the transmission mechanism of the actual system is mostly elastic components, which will cause the mechanical resonance of the system, which will lead to the deterioration of the system performance, so it is more important to identify the parameters of the dual inertia elastic system. The parameter identification of double inertia elastic system can be divided into equivalent single inertia identification method. This paper analyzes the basic idea of each identification method of double inertia elastic system, compares their advantages and disadvantages, and analyzes the application of identification algorithm in various industrial fields. Summarize the existing research results and the problems to be solved, and look forward to the future research direction.
