In this study, the 30x24x24 wall cabinet challenges of the controller design of a class of Uncertain Switched Neutral Systems (USNSs) in the presence of discrete, neutral, and time-varying delays are considered by using a robust observer-based control technique.The cases where the uncertainties are normbounded and time-varying are emphasized in this research.The adopted control approach reduces the prescribed level of disturbance input on the controlled output in the closed-loop form and the robust exponential stability of the control system.

The challenge of parametric uncertainty in USNSs is solved by designing a robust output observer-based control and applying the Yakubovich lemma.Since the separation principle does not generally hold in this research, the controller and observer cannot be designed separately, sufficient conditions are suggested.These conditions are composed vibrating table for chocolate of applying the average dwell time approach and piecewise Lyapunov function technique in terms of linear matrix inequalities, which guarantees robust exponential stability of the observer-based output controller.

Finally, two examples are given to determine the effectiveness of the proposed method.
