中文摘要：
提出一种适用于非最小相位对象的改进型扰动观测（DOB）结构.通过新增两个控制器,该结构不但对标称性能控制器输出进行动态补偿,而且还补偿了系统输出反馈信号.因此,基于新DOB的控制结构不但能在低频段很好的抑制外部干扰,消除实际被控模型摄动对闭环系统的输出性能的影响,更重要的是提高了抑制高频测量噪声的能力.最后,讨论了该控制结构的内部稳定性和鲁棒稳定性.
英文摘要：
An improved disturbance observer（DOB） is proposed for non-minimum phase systems.In this structure,both the nominal performance controller output and the feedback signal from the system output are dynamically compensated by two additional controllers.Hence,the effect of the external disturbances in low frequency and the model uncertainties in system output are eliminated.Furthermore,the capability in suppressing the high frequency measurement noise is highly improved.Finally,the internal stability and the robust stability of the whole control system are discussed.
