Problems solved by technology

[0002] The electro-hydraulic servo control system is mainly realized by single-chip microcomputer or digital signal processor (Digital Signal Processors, DSP). When the control accuracy is relatively high, the control algorithm is often complicated, and the process of developing with the underlying language is complicated and costly, and the development cycle is long. , The system upgrade is difficult; and the electro-hydraulic servo control system mainly implemented by software, because WINDOWS is a non-real-time operating system, it seems powerless to solve the problem of real-time control

Description

technical field [0001] The invention relates to an electro-hydraulic servo control system and method for automobile road simulation. Background technique [0002] The electro-hydraulic servo control system is mainly realized by single-chip microcomputer or digital signal processor (Digital Signal Processors, DSP). When the control accuracy is relatively high, the control algorithm is often complicated, and the process of developing with the underlying language is complicated and costly, and the development cycle is long , The system upgrade is difficult; and the electro-hydraulic servo control system mainly implemented by software, because WINDOWS is a non-real-time operating system, it seems powerless to solve the problem of real-time control. Contents of the invention [0003] The purpose of the present invention is to solve the above problems and provide an electro-hydraulic servo control system and method for vehicle road simulation. [0004] In order to achieve the a...
