摘　　要：传统的无差拍控制是精确数学模型的控制方法,其控制特性受系统参数变化影响较大。为了提高系统的跟踪精度,提出在线辨识参数的改进无差拍控制策略。分期实时地修正控制参数,使其对系统参数的变化具有良好的适应性,从而有效地改善了系统的跟随性能。The traditional deadbeat control is of mathematical model control method,the control property of which is greatly influenced by the system parameters. An improved deadbeat control stra-tegy is presented,in which the on-line identification parameter method is used and the controller parameters are real-time corrected. As a result,the controller is adaptable to system parameter chan-ges and its tracing property is effectively improved.
