通常认为动态速度刚度低是二次调节系统，乃至泵控系统致命的弱点，因而寻求提高二次调节系统的动态速度刚度的基本方法，进而用于二次调节系统的控制器设计，具有很大的理论与实用价值。本文采用仿真方法研究各种基本校正措施对二次调节系统动态速度刚度的影响，并得到一些有益的结论。
It is generally considered that the low dynamic speed stiffness is a fatal weakness of the secondary regulation system and even the pump control system. Therefore, the basic method of improving the dynamic speed rigidity of the secondary regulation system is sought, and then the controller design for the secondary regulation system has a large The theory and practical value. In this paper, the impact of various basic corrective measures on the dynamic speed stiffness of secondary regulation system is studied by simulation method, and some useful conclusions are obtained.
