FES脚踏车电机辅助系统的速度控制
Speed control of FES cycling with motor assist
【摘要】 以现有FES(functional electrical stimulation,功能性电刺激)脚踏车系统为基础,通过加入辅助电机,实现对FES脚踏车系统的速度控制。采用辨识方法,获得了被控对象的数学模型,并提出一种实用性强且计算量较小的极点配置自校正控制的新方法,设计了专用速度控制器。在matlab/simulink中进行了跟踪性能测试和抗干扰测试,仿真和实验结果表明系统的响应特性和跟踪性能良好,抗干扰能力强。研究结果对工程应用具有较大参考价值。
【Abstract】 Based on the current FES cycling system,the speed of FES cycling system was well controlled by adding motor assist.Mathematical model of the controlled plant was achieved by identification.And a new pole placement self- tuning controller was designed by a proposed algorithm with simple and less calculation.Speed tracking and disturbance rejection were tested in matlab/simulink.The results of simulation and experiment showed that the system was with good tracking performance and strong disturbance rejection.This research can provide a reference to engineering application.
【Key words】 FES cycling; motor assist; speed control; system identification; pole placement;
