Adaptive control effect analysis with parameters not totally identified

In view of the fact that the parameters can not be fully identified, which is frequently occurred in real adaptive parameter identification, this paper makes a deep analysis and studies the effect of the adaptive control law on the situation that parameter is not fully identified. In order to simplify the problem, this paper selects a class of first order systems with unknown parameters, the controller design and numerical simulation analysis are carried out by using the method of non adaptive control and adaptive control method, the results show that the adaptive control can replace the integral control, which can eliminate the steady-state error of the system.
