摘　　要：在"人—技"协同进化的教育发展态势下,如何有效促进教育形态的转变和教育质量的提升[1]。物理学习空间中的学习支持服务亟待重塑,在数字化技术支撑下,将传感技术引入到物理学习空间结合学习分析技术,获取学习者生理数据,推测其学习状态(情绪、注意力、嗜睡),提高学生的学习体验和协助教师实时监控,由于传感器容易受到个体无关学习生理信号的干扰,引起系统的不稳定性,该文基于MATLAB控制工具箱设计串联滞后—超前校正装置,并对仿真结果进行分析比较,该方法不但简化了控制系统校正的过程,提高了系统的稳定性。How to effectively promote the transformation of educational form and the improvement of educational quality under the situation of"human-technology"co-evolution of educational development.Learning support services in the physical learning space need to be reshaped urgently.Supported by digital technology,sensor technology is introduced into physical learning space and combined with learning analysis technology to acquire learners'physiological data,speculate their learning state(emotion,at⁃tention,sleepiness),improve students'learning experience and assist teachers to monitor in real-time.Sensors are vulnerable to in⁃dependent learning.The disturbance of physiological signals causes the instability of the system.In this paper,a series lag-lead correction device is designed based on the control toolbox of MATLAB,and the simulation results are analyzed and compared.This method not only simplifies the process of control system correction,but also improves the stability of the system.
