Improved Relative Coupling Control with Second-Order Consensus Compensation for Multi-PMSMs

This paper presents the implementation of improved relative coupling control (IRCC) with PI controller (PIC), velocity coupling compensation(VCC) and second-order consensus compensation (SCC) for speed synchronization control of multiple permanent magnet synchronous motors (PMSMs). Virtual network topology is constructed in SCC, distributed cooperative second order consensus protocol is utilized with leader-followers type for the compensation of PMSM control signal. To verify the validation of the IRCC, compare with traditional relative coupling controller is investigated. The results of simulation are provided to demonstrate the effectiveness of the proposed IRCC on stable synchronization with no load and load situations.
