AI Technical Summary
Technical Problem
Traditional PI controllers have only two parameters, which makes them less versatile and less effective at suppressing mechanical resonance, especially in complex two-inertial systems.
Method used
By combining PI control and a notch filter, a servo system transfer function is constructed. Through the relationship between design parameters and characteristic parameters and design constraints, the simultaneous adjustment of three control parameters is achieved, including the optimization of the proportional coefficient, integral coefficient, and notch filter attenuation coefficient.
Benefits of technology
It achieves highly applicable resonance suppression, improves the response performance of the servo system, and reduces the difficulty of parameter tuning.

Abstract
本发明提供了一种结合PI控制和陷波器的伺服系统参数整定方法及装置，属于工业控制领域，其方法包括：构建结合PI控制和陷波器的待控制伺服系统的系统传递函数；对系统传递函数按预设设计试样进行整定得到设计传递函数，并确定设计传递函数中设计参数与特征参数的关系式以及设计约束；在设计约束下设定设计参数的值，根据设计参数的值求解设计传递函数得到待控制伺服系统的控制参数。本发明通过将陷波器引入传统PI控制的伺服系统，进行三控制参数同时可调的伺服系统谐振抑制，实现高适用性的谐振抑制效果；进一步的，本发明通过设计试样整定系统传递函数，使三控制参数均可通过计算式求解，降低参数整定的难度，提高系统响应性能。
