摘　　要：将时滞滤波器与位置反馈环节相结合提出闭环时滞滤波控制策略,不仅能阻止操作命令向系统中注入能量,而且能阻尼掉不确定性因素注入系统中的能量,从而有效抑制二阶振荡系统的残留振动。与开环时滞滤波技术相比,有更强的参数鲁棒性和抗外界干扰能力。A closed-loop time-delayed filtering control scheme, which combines a time-delayed filter with position feed-back compensation, is proposed for suppressing the residual vibration of two-order oscillation systems. The time-delayed filter prevents the operator from inadvertently adding energy to the system through the commands, and removes the energy that has entered into the system due to unavoidable uncertainties. As a result,the residual vibration will be suppressed the residual vibration. Compared with the open-loop time-delayed filter the robustness and disturbance resistance of the closed-loop filter are strengthened.
