摘要
介绍了一种用于生物芯片血液蛋白自动检测仪的伺服控制系统,该系统使用机械臂控制系统为平台,以伺服电机为主要驱动装置。本文建立了该机械伺服控制系统模型,对模糊自整定PID控制算法进行了研究,并将其应用到系统中,在MATLAB软件中进行仿真,以实现系统对机械臂高精度定位的要求。仿真结果表明,机械臂模糊控制系统定位精度高,并且较常规PID具有更强适应性,发挥了传统控制与Fuzzy控制各自的长处,参数自适应模糊PID控制能使系统达到满意的控制效果。
In this paper, it presents a mechanical arm control system, which is based on an automatic analyze instrument for test of blood protein with biochip. The system uses robotic arm control system as a platform , arid servo motor as the main drive. In this paper, the servo control system model is established and the fuzzy adaptive PID control algorithm is researched. The algorithm is applied to the system and simulated in the Matlab software , which is used to achieve high accuracy orientation of the arm control system .The simulation results shows that the control system has high accuracy, and the fuzzy adaptive PID control algorithm is more adaptable than the conventional PID. It plays the respective strengths of the traditional control and Fuzzy control .The parameter adaptive fuzzy PID control make the system achieve satisfied results.
