Comparison of the Characteristics of Cost-Oriented Designed High-Speed Low-Power Interior PMSM

“…This work was part of a hybrid electric vehicle project [9][10][11], and the choice of this type of machine was no accident. Additionally, the salient-pole permanent-magnet synchronous machine seems to be the best choice for a hybrid electric vehicle, because the total average torque produced by this machine is the sum of the synchronous and reluctant torques [12][13][14]. Furthermore, synchronous permanent-magnet motors tend to have a very high initial cost compared to other types of motors due to high magnet prices, but their prices are falling as technology develops.…”

This research work deals with the problem of controlling a salient-pole permanent-magnet synchronous motor (SP-PMSM) used in hybrid electric vehicles. An adaptive nonlinear controller based on the backstepping technique is developed to meet the following requirements: control of the reference vehicle speed in the presence of load variation and changes in the internal motor parameters while keeping the reliability and stability of the vehicle. The complexity of the control problem lies on the system nonlinearity, instability and the problem of inaccessibility to measure all the internal parameters, such as inertia, friction and load variation. For this issue, an adaptive backstepping regulator is developed to estimate these parameters. On the basis of formal analysis and simulation, as well as test results, it is clearly shown that the designed controller achieves all the goals, namely robustness and reliability of the controller, stability of the system and speed control, considering the uncertainty parameters’ measurements.

“…Permanent magnet synchronous motor (PMSM) applications tend to have a higher initial cost. Hence, they may offer a smaller size for more compact mechanical packages, desirable torque to inertia ratio, high reliability, and more controllability [1], [2]. Recently, the high-performance PMSM Wei drive system has been developed, which increases their reputation in electric vehicle applications [3][4][5][6][7].…”

Operating in the high-speed range is necessary for high-performance permanent-magnet synchronous motor (PMSM) drives. However, due to the back electromotive force effect, the PMSM is approaching the voltage limit at field decreasing scope. This paper presents a new flux-weakening scheme along with an improved vector control strategy to alleviate the influence of this problem. Control parameters of the antiwindup proportional and integral (AWPI) controller are optimized off-line in relying on an adaptive velocity particle swarm optimization (AVPSO) algorithm. The AVPSO algorithm considers the summation of AWPI measurement error which is the objective function of the optimization problem without knowing the transfer function of the plant. Hence, the tuned flux-weakening controller with a filter is used to set the flux level without saturating the current controllers. Meanwhile, the other controllers of inner and outer loops award a great dynamic and steady-state performance for the PMSM. In the proposed scheme, the flux-weakening control is not dependent on machine parameters that adapts the flux level automatically and provide a fast transition between the constant torque region and the field-weakening region. Effectiveness and advantages of the proposed scheme are presented in this paper through both simulation and experimental results.
