| 为了实现对电液伺服系统进行快速、准确以及较为平稳的控制，提出了基于单片机与改进PID的智能电液伺服控制系统。通过对电液伺服系统的主要组成进行分析，并根据液压控制理论，得出了电液伺服系统中电液伺服阀等机构的数学模型。利用MSP单片机作为主控器，以接收位移传感器采集到的实时位移值，根据该值对电液伺服阀的开度进行控制。引入PID控制器，通过神经网络算法对PID控制器进行改进，设计电液伺服控制系统的控制策略，以实现电液伺服控制系统的智能化。通过Matlab/Simulink软件对所提方法进行了仿真实验，结果显示，所提方法不仅能够较为快速、准确地对电液伺服系统进行控制，而且控制过程较为平稳，具有良好的控制效果。 |

| In order to control electro-hydraulic servo system quickly, accurately and smoothly, this paper presents an intelligent electro-hydraulic servo control system based on single chip computer and improved PID. By analyzing the main components of the electro-hydraulic servo system and according to the hydraulic control theory, the mathematical model of the electro-hydraulic servo valve and other mechanisms in the electro-hydraulic servo system is obtained. The MCU is used as the main controller to receive the real-time displacement value collected by the displacement sensor and control the opening of the electro-hydraulic servo valve according to the value. The controller is introducedand improved by the neural network algorithm to form the control strategy of the designed electro-hydraulic servo control system, so as to realize the intellectualization of the electro-hydraulic servo control system. The simulation results show that the proposed method can not only control the electro-hydraulic servo system more quickly and accurately, but also control the process more smoothly and has a better control effect. |
