有滞后环节的系统的闭环鲁棒辨识方法

Robust Closed-loop Identification of Continuous Systems with Dead-time from Step Response

提出一种新的针对带滞后环节的任意阶系统的闭环辨识方法。通过“三步法” ,实现在闭环条件下的被控制对象的传递函数参数的辨识 ,所提出方法具有很强的鲁棒性。

This paper proposes a new robust closed loop identification algorithm to continuous systems with dead time.The transfer function of the system can be identified in the closed loop condition,with the algorithm proposed in this paper.And the resulting parameter estimation is very robust to disturbance and measurement noise in the output.Simulation results illustrate the accuracy of the proposed algorithm.
