Calculation of the performance of the dual three-phase permanent magnet brushless machine system using matrix tensor approach

Dual three-phase permanent magnet brushless machine (DTPPMBLM) system is the key subsystem in electrically powered actuation system. The strong mutual coupling and nonlinearity of DRPMBLM as well as its drive make it very difficult to obtain a comprehensive mathematical model for the behavior of the system. This paper proposes a new method to modeling the DTPPMBLM drive system based on the matrix tensor approach (MTA). The switching mode of the power converter is analyzed and modeled theoretically, based on which the DTPPMBLM and control system is coupled with MTA. Then, the MTA model and the two dimensional finite element analysis (2D-FEA) model are used to simulate the various steady-state and transient performances of the 2 × 1.8kW DTPPMBLM. Comparison of the simulation results of the MTA model and the 2D-FEA model verifies the feasibility of MTA. The results of this study suggest that MTA may be an efficient approach for the coupling of the DTPPMBLM drive.
