dc.descriptionIn view of these limitations, this thesis aims to introduce various analytical simplified direct voltage maximum torque per ampere speed control approaches. Initially, a simple current sensing-based direct voltage MTPA control is introduced for IPMSM propelling electric vehicles. The designed strategy’s voltage amplitude and angle control laws are analytically derived from the motor’s electrical model based on measured stator current, eliminating the need for torque estimation, control law approximation, or iterative solution. Thus, MTPA trajectory tracking can be guaranteed in all operating ranges, in addition to improved computational efficiency. Direct Voltage MTPA techniques are model-based approaches that depend heavily on time-varying electrical parameters. Furthermore, shaft speed and position are of great importance in these strategies. However, integrating mechanical sensors for speed and position presents drawbacks such as high costs, mounting space needs,
dc.description.abstractWith the significant advancements in permanent magnet materials manufacturing, control techniques, and processing capabilities, permanent magnet synchronous motors (PMSMs) have become more attractive and competitive for various industrial applications. In the constant torque region, a commonly adopted technique for maximum torque utilization of PMSMs is known as maximum torque per ampere control (MTPA). This technique aims to achieve the desired torque with minimal current consumption. Conventional MTPA control approaches typically utilize PI-based cascaded control loops, which lead to significant time costs in practical applications and burden the overall control performance. In contrast, direct voltage control methods (DVC) are alternative techniques to track the MTPA points by directly manipulating the voltage vector amplitude and angle, eliminating the need for cascaded regulation. However, the few developed direct voltage control methods still rely on complex torque estimation, numerical approximations of a given motor, lookup tables, and lengthy iterative calculations to determine its control laws.
