“…In [13], a nonlinear observer was designed using a Lyapunov function that used the electrical and mechanical parameters and was compared with an extended Kalman filter. In [14], a nonlinear Luenberger observer was designed using the flux maps of the machine. And in [15], model-free adaptive control was used to avoid the electrical parameters altogether by only using the mechanical dynamic model and the position sensor.…”

Electrified transportation is a cornerstone of global decarbonization plans. However, high costs remain an obstacle. To address this, research has been undertaken to remove sensors and replace them with software. Simultaneously, with the volatility in pricing and supply of rare-earth magnets, alternatives to the permanent magnet synchronous machine are being sought. With fundamentally similar performance and the benefit of a controllable flux, the wound rotor synchronous machine is a promising alternative. This paper presents a linear Luenberger observer using the model incorporating rotor flux dynamics and nameplate parameters. It is shown that the wound rotor synchronous machine is observable with only one current sensor, either on the rotor or the stator. However, to overcome parameter error issues, a minimum of one current sensor on the rotor and one on the stator is deemed necessary to provide corrective integral feedback. Simulation results demonstrate that the designed observer can accurately estimate the rotor and stator currents in the presence of model error with the minimum sensor complement during transient and steady state operation.

“…Considering the transient states, a direct voltage MTPA without current sensing is implemented in [25] to enhance the control system's performance. As a transition to a sensorless technique, the current components are calculated from the motor's electrical model and directly injected into the control loop, which may exhibit a significant noise in the absence of any estimator [28]. Furthermore, the control signals are extracted based on longwinded calculations followed by many iterations to reach the optimum values, increasing the computational burden of the control system.…”

This paper introduces a current sensorless speed control method for interior permanent magnet synchronous motors (IPMSMs) to track the maximum torque per ampere (MTPA) trajectory. Unlike traditional cascaded control structures, current measurements and inner regulation loops are eliminated. Instead, the MTPA is attained by directly adjusting the voltage vector amplitude and angle. An analytical formulation based on the motor voltage model is developed to extract the optimal voltage amplitude to run the motor within the MTPA operating points, disregarding any control law approximation or lookup tables-based numerical solutions. As a result of excluding current measurements and regulation loops, a one-speed controller is required. This leads to a significant reduction in control system complexity. Moreover, the simple structure of the control system highly qualifies it for cost-effective implementation of IPMSM applications. The validity of the designed control method is confirmed experimentally using a 5Hp IPMSM. The experimentally obtained results are compared to the conventional field-oriented MTPA (FOC) to highlight the effectiveness of the suggested control system considering different operating conditions. Additionally, the MTPA trajectory tracking accuracy is quantitatively assessed using two performance metrics.INDEX TERMS Interior permanent magnet synchronous motor (IPMSM), current sensorless, maximum torque per ampere (MTPA), direct voltage control.

This study investigates the nonlinearities in three-phase inverters for SiC-based systems and compares their performance to IGBT-based systems. An analytical model of inverter voltage distortion is developed, which accounts not only for dead time (td), switching delay time, switching frequency (fs), and voltage drops of power devices, but also for output parasitic capacitance (Cout). Experimental tests validate the model, which provides a more accurate estimate of the inverter’s output phase voltage distortion. The power device characteristics are obtained from datasheets, while Cout is determined through experimentation. Three-phase inverters with varying switching frequencies, fundamental frequencies, and dead-time values are used in simulations and experiments to determine the influence of nonlinearity on phase voltage deviation and current distortion. The results show that, due to SiC devices’ faster switching time, the phase voltage deviation and phase current distortion are lower in SiC-based inverters than in IGBT-based ones for high-frequency applications, as the dead time can be reduced.
