This paper addresses the distributed output regulation problem of switched multi-agent systems subject to input saturation. Two types of independent switching signals are considered in this work. Each agent is described by a switched linear system with an average dwell time and input saturation. The interconnection topologies are also switched subject to dwell time. Since not every agent can obtain the information of the exosystem, the distributed feedback controller is designed. An agent-dependent average dwell time method with an adjustable parameter based on algebraic Riccati equations is proposed to solve the output regulation problem. Finally, two examples are provided to illustrate the electiveness of our results.
