Abstract: In a control method of a dual three-phase permanent magnet synchronous motor by alternately performing sampling and control procedures, sampling instants, vector loading instants, and reference value tracking instants of two sets of windings alternate in two halves of a sampling period, and the equivalent sampling frequency of the motor drive system is doubled and the digital delay and the predictive horizon are halved without changing the sampling frequency of a single set of three-phase windings. In addition, by a two-layer MPC strategy, a deficient-rank problem is settled that the controlled dimensionality of the system is reduced to two dimensions but the motor control objective is still four dimensions caused by the method with controlling a dual three-phase permanent magnet synchronous motor by alternately performing sampling and control procedures.
