Application Of TC1782in Permanent Magnet Synchronous Motor Control System For Vehicle

With the continuous advancements in the automotive industry, people are beginning to pay more and more attention to environmental problems and economic issues caused by the consumption of gasoline. As environmental conditions decline and gasoline prices rise, hybrid electric vehicles (HEVs) are surely becoming the future of the automotive industry. The vehicle motor drive system, as one of the key technologies of HEV, will directly affect an automobile’s dynamic performance and fuel consumption. This paper will discuss the permanent magnet synchronous motor (PMSM) for vehicles, using TC1782to design the vector control system and verified through experiments.Firstly, the paper will introduce the difference between semiconductor chip for industrial and semiconductor chip for vehicles, and analysis the application status at home and abroad of semiconductor chip for vehicles.Secondly, based on Infineon’s32-bit automotive microcontroller TC1782to design the PMSM vector control system. Introduce internal structure and functional characteristics of TC1782.Using DAvE, a development tool for visual programming to develop the chip.Thirdly, the permanent magnet synchronous motor is an ideal model of a vehicle motor as it has characteristics of high efficiency. This paper will introduce a mathematical model for motor vector control in a different coordinate system as well as explain the development method of the motor control system using DSP.Fourthly, the paper will introduce the detail configuration of GPTA to create PWM signal. Using Tasking to debug the software.Finally, the entire motor control system, both hardware and software, is tested through experiments. The motor is able to perform smoothly in the system and the experiments also confirm the expected torque and speed of the motor to be accurate.
