Performance Control for Interconnection of Identical Systems: Application to PLL network design

International audienceIn this paper, the problem of the control law design for interconnected identical systems ensuring the global stability and the global performance properties is under consideration. Inspired by the decentralized control law design methodology using the dissipativity input–output approach, the problem is reduced to the problem of satisfying two conditions: (i) the condition on the interconnection and (ii) the condition on the local subsystem dynamics. Both problems are efficiently solved applying a (quasi‐) convex LMI optimization and standard H∞ synthesis. The proposed design methodology is applied to the control law design of a synchronous PLL network

Control Law Design for Distributed Multi-Agent Systems

In this paper, the problem of control law design for decentralized homogenous Multi-Agent systems ensuring the global stability and global performance properties is considered. Inspired by the decentralized control law design methodology using the dissipativity input-output approach, the problem is reduced to the problem of satisfying two conditions: (i) the condition on the interconnection and (ii) the condition on the local agent dynamics. Both problems are e fficiently solved applying a (quasi-) convex optimization under Linear Matrix Inequality (LMI) constraints and an H infinity synthesis. The proposed design methodology is applied to the control law design of a synchronous PLLs network
