摘要
鉴于叶片检测系统对运动控制系统高精度的要求,分析叶片检测系统的运动控制方式。基于IMAC400控制卡研究其PID参数调整原理,设计fuzzy logic的PID自整定算法,比较传统PID与模糊自整定PID的控制性能。实验结果表明:在抛物线响应中,常规PID控制的最大跟随误差为-8.602 9,而模糊自整定PID控制最大跟随误差为-8.492 2。模糊自整定PID技术对运动控制系统的稳定性及精确度均有很大的提升。
This paper proposes the PID self-tuning algorithm based on fuzzy logic as a response to the higher precision requirements imposed by the blade detection system on motion control system. The algorithm hinges on the analysis of the motion control mode Of blade detection system and the study of the PID parameter adjustment principle based on IMAC400 control card. The viability of the algorithm is demonstrated by performing the experimental contrast between the conventional PID and the fuzzy self-tuning PID technology in terms of control performances. The results suggest that in the parabolic response, the fuzzy self-tuning PID technology exhibits the maximum controlled tracking error of -8. 492 2, compared to - 8. 602 9 for conventional PID. The fuzzy self-tuning PID technology holds promise for a significant improvement in the stability and precision of motion control system.
