“…This means the output power is lower than the maximum output power available for the corresponding speed in the conventional method. Figure 12b shows the waveform of the experimental result when the q-axis current is compensated using Feedforward1 and the PI controller under the same conditions as in Figure 12a [17,18]. As shown in the waveform of the experimental result, V mag increases with i r qs , which is the q-axis current, increasing owing to i * qs c omp .…”

“…However, since this kind of method has a slow response and the current commands are incorrect when the voltage error is small, additional compensation is required. In [18], an additional feedforward compensation method is proposed in order to improve the performance of interpolation error compensation, proposed in [17], based on the voltage error. However, even with this method, the additional compensation was not effective when the value of the voltage error was small, and the q-axis current response was not fast enough when the reference current changed very fast.…”

“…This paper proposes an improved interpolation error compensation method. In this study, a voltage feedforward controller and a current feedforward controller are added to the interpolation error compensator proposed in [17,18]. The proposed algorithm was verified experimentally based on a motor-generator setup in laboratory.…”

This paper proposes a compensation method for interpolation error of the maximum power control of a PMSM control system that generates current commands through a look-up table. A torque control system using a look-up table created through experiments has superior characteristics, such as control stability and torque accuracy, compared to a system that executes torque control via a linear controller based on modeling. However, it is impossible to generate information on all the currents for the output torque in the table. Therefore, because the data stored in the look-up table have a discrete characteristic, they are linearly interpolated to generate a current command for the torque command. However, the PMSM current trajectory is generally elliptical, which causes an error owing to linear interpolation, reducing the maximum output power. In particular, when the table data are insufficient, such as in the high-speed operation range, the reduced maximum output cannot be ignored. This paper proposes a compensation method for the interpolation error using two feedforward compensators and a PI controller, which was verified through experiments.

This paper discusses the process of developing a novel and robust algorithm for an interior permanent magnet synchronous motor controller. This is necessary for the simplification of the setting of control parameters and maintaining the proper operation of the motor. A 3D torque lookup table was used in which two inputs were considered, i.e., accelerator movements and the motor rotational speed. These two inputs allowed the lookup table to generate a specified torque at any motor rotation, which was then fed-forward to the field-oriented control and space vector pulse width modulation algorithm. Modeling, simulation, and experimental tests were performed to design and validate the proposed controller. The experimental validation shows that the proposed controller worked as intended. This was indicated by its ability to control the motor to obtain a 7% higher torque output than in the simulation in the constant torque region. In the field-weakening region, the controller could make the motor reach a maximum speed of 5500 RPM. There was only an 8% difference compared to the simulation (6500 RPM). In terms of maximum power generated, the controller was able to match the simulation output with only a 5% difference.

“…A new effective use and operation of fuzzy-logic controller-based two-quadrant operation of a permanent magnet brushless DC motor drive system for multipass hot-steel rolling processes is proposed in [21], with validation through simulation and experimental tests provided. Another study [22], proposed a field weakening control method that employs interpolation error compensation of the look-up table based PMSM method. As in the majority of these studies, the improvement reached by using the proposed method is validated through experimental and simulation tests.…”
