摘要

研究了一种基于估计量的终端滑模控制系统。提出了一种精确估计量来精确估计有限时间内的未知不确定性。利用精确估计器的输出设计连续无抖振终端滑模控制。证明了闭环系统达到零跟踪误差所需的时间是有限的。实验结果表明，采用实时数字信号处理器(DSP)实现磁悬浮系统的控制性能。

Exact-estimator-based terminal sliding mode control system design

This paper investigates an estimator-based terminal sliding mode control system. An exact estimator is proposed to exactly estimate the unknown uncertainties in finite time. The output of the exact estimator is used to design a continuous chattering free terminal sliding mode control. The time taken for the closed-loop system to reach zero tracking error is proven to be finite. Experiment results are presented, using a real time digital-signal-processor (DSP) based electromagnetic-levitation system to implement the control performance.
