摘要
为了解决工业伺服控制系统PID控制参数设计及与滤波器的参数整定困难的问题,展开弹性传动系统模型分析与系统仿真,探讨扩充参数平面法的PID参数设计调节与应用,分析惯性比及陷波器对系统阻尼特性的影响.同时,针对呈现欠阻尼状态,在PID控制系统的基础上引入陷波器,采用同方法对控制参数进行整定,对比引入陷波器前后的振动抑制效果,验证了传统陷波器效果及设计方法的有效性.展示的控制方法与设计方法,对高阶弹性伺服系统的振动抑制研究具有理论指导和优化设计的效果.
Abstract
For industrial servo control systems,PID tuning method based on the extended parameter plane method is proposed to design parameters of controller and filter.A two-inertia elastic system model is estab-lished,and its inertia rate is used to design reference,and the feasibility of the PID design method is verified through simulation analysis.The control of 5th-order systems with three parameters is achieved,and the im-pact on different inertia ratios is analyzed and summarized.At the same time,a notch filter is introduced for underdamped case,the vibration suppression effect with or without notch filters is compared,and the effec-tiveness of the notch filter effect and design method are verified.It is showed that the presented method is very effective for high-order system.
