<p>This paper focuses on developing a general method for stabilizing uncertain switched systems with extended comprehensive asynchronous switching in the presence of disturbances, based on an observer and under the average dwell time condition. To demonstrate the effectiveness of the proposed approach, dynamic output feedback and dynamic state feedback controllers are designed for such systems. The main contributions of this paper can be summarized in three parts: (1) Introduction of the extended comprehensive asynchronous switching concept. (2) Design of linear controllers for both linear and nonlinear switched systems. (3) Controller design considering the simultaneous presence of disturbance, extended comprehensive asynchronous switching, uncertainty, and an observer. The term “extended comprehensive asynchronous switching” refers to the condition in which each controller can be activated with any subsystem within asynchronous intervals. This increased flexibility enables the design of controllers for a broader class of switched systems. The effectiveness of the proposed methods is verified through simulation.</p>
