However, traditional control methods have certain limitations in dealing with time delay problems and cannot meet the requirements of practical systems. Therefore, this paper proposes a new robust passive control method to deal with the control problem of uncertain time-delay systems.In this paper, we first briefly introduce the general form and characteristics of uncertain time-delay systems, and discuss the limitations of current time-delay control methods. Then, relying on the stability and robustness of passive control, a new robust passive controller based on Lyapunov function is constructed.In order to verify the effectiveness of this method, this paper controls several uncertain time-delay systems through numerical simulation and experimental simulation. The results show that this robust control method can achieve stable operation that meets performance requirements for uncertain time-delay systems. Compared with traditional time-delay control methods, this method has better stability and robustness.Keywords: uncertain time-delay system; robust passive control; Lyapunov function; stability; robustness.
