| 總結: | The application of electric motors has spread in various lives of modern
society today, one of which is transportation. One type of motor that is often used
is the Brushless DC (BLDC) motor. To drive a BLDC motor, a controller is needed
so that the motor has good performance when operating. This final project research
aims to create and analyze the Maximum Torque Per Ampere (MTPA) control
strategy algorithm, which is a control strategy that aims to minimize motor phase
current at a torque output, and the appropriate control system for a 120 kW BLDC
motor, both as torque and speed control. The Mercedes-Benz OF-917 bus was
chosen as a benchmark to make it easier to determine load parameters. The results
of this study are the MTPA strategy requires a smaller phase current than the
Modified Field Oriented Control (MFOC) method with a magnitude of 0.14% to
1.27% with a performance that is not much different. The regenerative braking
algorithm has been simulated with the results of having the same performance as
the MFOC method and when the source is reduced, the motor performance is not
reduced too significantly. This MTPA control strategy is better used for larger or
equal to 250 Nm of output torque because the torque ripples and currents are smaller
than the MFOC method. |
