摘　　要：本文介绍了一种带降维状态观测器的滑模控制器,且进行了Matlab仿真。在不考虑观测误差的情况下,设计了滑模函数趋近律,用观测量替代实际值,证明了滑模函数在考虑观测误差下的收敛性好。考虑观测误差后,可直接得到误差的表达式,通过Laplace变换后s域表达式的误差可收敛到0。滑模函数的趋近律中不含非连续项,不会发生抖振,从仿真结果中可以看出,其具有良好的跟踪效果。带降维观测器的滑模控制器设计简单,性能良好,鲁棒性强,易应用于实际场景。This paper introduces a sliding mode controller with reduced dimension state observer,and carries out Matlab simulation.The sliding mode function convergence law is designed without considering the observation error,and the actual value is replaced by the observation,and it is proved that the convergence of the sliding mode function is good under considering the observation error.After considering the observation error,the expression of the error can be obtained directly,and the s-domain expression can be derived by Laplace transform to converge to O.The convergence law of the sliding mode function does not contain discontinuous terms,and no jitter occurs,and the good tracking effect can be seen from the simulation results.The sliding mode controller with reduced dimensional observer is simple in design,good in performance,robust and easy to apply in practical scenarios.
