-This paper proposes an improved sensorless control to estimate the rotor position of an interior permanent magnet synchronous motor. A phase-locked loop (PLL) is used to obtain the phase angle of the grid. The rotor position can be estimated using a PLL based on extended electromotive force (EEMF) because the EEMF contains information about the rotor position. The proposed method can reduce the burden of calculation. Therefore, the control period is decreased. The simulation and experimental results confirm the effectiveness and performance of the proposed method.

“…Based on the arrangement of the permanent magnet, a PMSM is fundamentally divided into an interior permanent magnet synchronous motor (IPMSM) and a surface-mounted permanent magnet synchronous motor (SPMSM). Because the magnet is mounted inside the rotor, an IPMSM is durable during high-speed operation compared with a SPMSM [1][2][3][4].…”

“…The angle of the current vector is changed with the parameter variation because the angle of the minimum current vector relates to d-axis and q-axis inductance. Unfortunately, the stator resistance, inductance and magnet flux are sensitive to the variation of temperature [1][2][3][4]. Variation of d-axis and q-axis inductance can decrease effectiveness of the MTPA control and current controller.…”

-This paper presents estimation of d-axis and q-axis inductance of an interior permanent magnet synchronous motor (IPMSM) by using an extended Kalman filter (EKF). The EKF is widely used for control applications including the motor sensorless control and parameter estimation. The motor parameters can be changed by temperature and air-gap flux. In particular, the variation of the inductance affects torque characteristics like the maximum torque per ampere (MTPA) control. Therefore, by estimating the parameters, it is possible to improve the torque characteristics of the motor. The performance of the proposed estimator is verified by simulations and experimental results based on an 11kW PMSM drive system.

SummaryIn this paper, saturation and temperature variation effects on control of permanent magnet synchronous motors are investigated in terms of motor loss on different control methods including "unity power factor," "maximum torque per ampere," and "loss minimization." Afterwards, a hybrid compensation method is proposed to improve the response time to reach maximum efficiency point. In the proposed method, to improve the response time to reach maximum efficiency point, initial value of optimum operating point is determined via model-based method. Then, based on perturb and observe method, d-axis reference current is changed step by step. Next value of d-axis reference current is determined via measuring direction of dc-link power variation. Also, the proposed hybrid method is compared with a conventional search-based method under different parameter variation and step load and reference speed implementation. The proposed hybrid compensation algorithm has been experimentally implemented and proved to be a practically useful method to improve the response time to reach maximum efficiency point under parameter variation and also under load and speed variation. | INTRODUCTIONAccording to energy prices and energy efficiency policies, energy saving has a great importance. However, electrical motors have great deal of power consumption; therefore, reducing loss of electrical motors by just a few percent has a great impact on total power consumption. Although permanent magnet synchronous motors (PMSMs) are widely used in industry due to high efficiency, high energy density, low torque ripple, fast dynamic response, etc. [1][2][3][4][5][6] Controlling the PMSMs can be performed via different control methods. Some of these methods such as i d = 0 or search-based loss minimization control methods are independent of motor parameters. [7][8][9] In contrast, in some methods,
