To calculate the magnetic saturation and iron loss, the Flux-Based PMSM block uses the inverse of the flux linkages. To obtain the block parameters, you can use finite-element analysis (FEA) or measure phase voltages using a dynamometer. By default, the block sets the Simulation Type ...
The Flux Based PM Controller block implements a flux-based, field-oriented controller for an interior permanent magnet synchronous motor (PMSM) with an optional outer-loop speed controller. The internal torque control implements strategies for achieving maximum torque per ampere (MTPA) and weakening ...
The improved sliding mode observer utilizes the flux model of the PMSM to enhance the accuracy of electrical angle estimation, thereby reducing the estimation errors and improving the control of the current loop and speed. The RBF-PID controller ensures system stability while achievi...
Flux-weakening control of PMSM based on single current regulator has high dynamic performance. But the fixed given q-axis voltage decreases the motor's efficiency and load capability. This paper gives a new method of variable q-axis voltage. It can adjust q-axis voltage fully using the motor...

Figure 1. A block diagram of the proposed observer for the flux-based sensorless FOC of PMSMs based on the voltage model in the stator reference frame. The simplicity and filtering properties of the integrators make this observer highly desirable, especially in low-cost applications, but the ...
Then, two novel flux observers, second-order generalized integral flux observer (SOIFO) and second-order SOIFO are designed for the rotor flux estimation of PMSM. Based on second-order generalized integrator (SOGI) structure, the SOIFO can limit the dc component to a certain value...
Permanent magnet synchronous machines (PMSMs) have high efficiency, high power density, high torque-to-inertia ratio, and fast dynamic response. These features make this kind of machines very attractive for electric vehicle (EV) applications. However, because of their nature, i.e., constant magne...
