【摘要】：针对磁浮球系统的线性化数学模型,提出了1种模糊自适应预测函数控制(PFC)策略。在传统PFC的基础上设计了1个离散模糊控制器,在线调节该PFC的参考轨迹时间常数,以实现参考轨迹的自我调节。保持了传统PFC在线计算量小的优点,可以使系统达到更好的控制效果。仿真和基于d SPACE的实验结果均表明,该文的模糊自适应PFC策略能够实现小球的稳定悬浮,具有较好的快速性和较强的抗干扰能力,调节时间为2.07 s,时间乘绝对误差积分(ITAE)达到10.75。
[Abstract]:A fuzzy adaptive predictive function control (PFC) strategy is proposed for the linearized mathematical model of maglev ball system. Based on the traditional PFC, a discrete fuzzy controller is designed to adjust the reference locus time constant of the PFC on line. In order to realize the self-adjustment of the reference trajectory, the advantages of the traditional PFC on-line computation are kept, and the control effect of the system can be better. The simulation and the experimental results based on d SPACE show that, In this paper, the fuzzy adaptive PFC strategy can realize the stable suspension of the small ball, and has good rapidity and strong anti-interference ability. The adjusting time is 2.07 s and the time multiplication absolute error integral is 10.75.
