摘要
由于受常规数据处理单元(MCU、PLC等)矩阵运算能力的限制,目前模糊控制算法在实际应用中多采用离线计算、在线查表的方式来实现。但大量实践表明,这种方式往往会给系统带来稳态误差,从而限制了模糊控制在工程中的应用。通过对Mamdani型模糊推理本质原理的研究几何意义的基础上,设计了一种对数据处理单元性能要求不高、并可实现实时在线计算的模糊控制器,最后将其应用于基于运动控制卡的直线电机XY平台控制系统。实验结果表明,该控制器能有效地避免稳态误差,能更好地提高系统的可控性。
Be limited by the matrix operation ability of normal control CPU （e.g. MCU, PLC and so on）, the realization of fuzzy control always via the way of ＂calculate offline and inquire online＂ . Applications and practices have proved that such a realization method brings system steady-sate error, and limited the application range of fuzzy control. Based on the study of FC theory and the analysis of Mamdani fuzzy reasoning from geometrical meaning, a real-time fuzzy controller is designed and used in a Linear Motor XY platform control system based on motion control card. The results show that the real-time FC can avoid the steady-state error effectively and improve the controllability further.
