Summary:This article deals with designing and implementing a collaborative and decentralized control for synchronizing the angular speed tracking of a group of spatially distributed permanent magnet synchronous motors (PMSM). Via feedback linearization, acting as an internal loop, the dynamics of the PMSM rewrites on two subsystems: a subsystem of secondorder integrator and a subsystem of first-order integrator, which is considered an agent. Then, a decentralized collaborative control strategy is proposed, which solves the problem of leader-follower consensus for the multi-agent system and thus speed synchronization. Further, this article presents speed profiles formation among agents. The communication topology between agents is modeled using an undirected and connected graph. The decentralized control law incorporates the desired reference angular speed trajectory, employing a Bézier polynomial. The i-th agent transmits the angular speed trajectory information to its neighbor. The Matlab-Simulink/PSIM simulation results show excellent performance for angular speed consensus and for regulation and tracking tasks.
