Abstract-The paper deals with the maximum torque and speed of permanent magnet synchronous motor (PMSM) drives when the inverter output voltage is filtered by an LC filter with a cut-off frequency well below the switching frequency. According to steady-state analysis, the filter affects the performance of the motor drive especially at high speeds. The stator current is not equal to the inverter current, and due to the inverter current and inverter voltage limits, the torque-maximizing stator current locus differs from that of a drive without the filter. A field-weakening method is proposed for PMSM drives with an inverter output filter. The method is implemented and tested in a 2.2-kW PMSM drive. The experimental results agree well with the analysis, and validate the high-speed performance of the proposed field-weakening method.Index Terms-Permanent magnet synchronous motor (PMSM) drives, inverter output filter, field-weakening control, vector control.

“…In other words, it takes full advantage of electric torque with minimum copper loss, then acquires a high speed by sacrificing torque performance in the flux weakening region within safety boundaries [2,5]. The control references are derived by computing the intersection of the constant torque line and the voltage constraint locus [6][7][8]. Dating back to the 1990s, in [8,9], the operation region of a motor has already been divided by precalculating the current reference for each region and pre-settling the speed reference for operation interval switching.…”

Dating back to the 1990s, in [8,9], the operation region of a motor has already been divided by precalculating the current reference for each region and pre-settling the speed reference for operation interval switching. Based on this principle, numerous methods have been studied to compute the current control target from analytical equations which substantially control the terminal voltage of a motor.…”

Abstract:The nonlinearity and uncertain variation of machine parameters are always caused by cross coupling and magnetic saturation effects, which are easily neglected in the conventional control strategy. In this paper, a current trajectory control strategy (CTCS) is proposed to take the cross coupling and magnetic saturation effects into account under voltage and current constraints. It can be considered as a calculating method considering parameter variation and separating among each iteration step which treats the calculated result of the former step as the initial value of the next step. At first, the torque command is translated into the current reference. Then, the increments between the target value and real value of the torque and the voltage are respectively calculated, which are subsequently converted into the current modification vector in di d , di q framework for further analysis. In order to take the influence caused by cross coupling and magnetic saturation effects on the CTCS into consideration, self and mutual inductances are analyzed by finite element analysis (FEA). The results of the simulation and experiment show that the rapid response and robustness on reference speed variation could be achieved by employing the proposed CTCS, and the seamless switching between the constant torque and flux-weakening operation can also be realized.
