The Research of dSPACE Based on Hardware-in-the-Loop Simulation in Electro-Hydraulic Servo Control

摘要: 电液伺服控制算法一般采用软件编程的方法实现，其开发过程复杂，代码编写工作繁重，开发周期长。本文介绍了基于dSPACE的半实物仿真技术，利用MATLAB/Simulink的系统建模方法和dSPACE系统的软硬件环境，开发出以dSPACE为核心的电液伺服控制实验平台，在该平台上进行了电液伺服控制的试验研究，并利用ControlDesk进行了在线调参。实验结果验证了该实验平台的可靠性，并为研究更加复杂的控制算法提供了基础。

Abstract: The electro-hydraulic servo control algorithms are always achieved in the way of program, but the period of the project is long, and the process is complex because of hard working programming. A dSPACE-based hardware-in-the-loop simulation system is presented in this paper to demonstrate the direct use of MATLAB/Simulink in real-time control. Through the combination of these tools, an electro-hydraulic servo control platform based on dSPACE system is developed. The research of electro-hydraulic servo control is performed on this platform, and by the use of ControlDesk we can tuned the control parameters on line to adjust the performance of real-time system. The experiment result verified the reliability of the platform, which offers foundation for the design of more complex control algorithms.
