Predictive Current Trajectory Control for PMSM at Voltage Limit

Abstract: This paper presents a fast predictive current trajectory strategy for permanent magnet synchronous motors (PMSMs) at voltage limit. The current hexagon obtained from the voltage hexagon of the inverter represents the region that the currents can reach in the next switching periond. The nearest avaliable current point to the reference is solved by geometrical method on the current plane. The output of the proposed algorithm is divided into four cases according to the position of the current points. The algorith… Show more

“…The FSMPC is chosen as the current control strategy to track the MEA trajectory. Whereas, the FSMPC design on the digital processor requires the discrete-time model of the IPMSM [28,29]. Hence, the continuous-time IPMSM model can be into the discrete-time model with the forward Euler method, defined as follows.…”

“…Among various types of ac motors, the permanent magnet synchronous motors (PMSMs) are increasingly used in the industrial applications (e.g., electric vehicles (EVs), machine tools, industrial robots, home appliances, etc.) owing to their outstanding advantages such as high efficiency, compact size, low maintenance cost, high power density, high reliability, and high torque-to-inertia ratio [1][3]. In the surfacemounted PMSMs (SPMSMs), it is necessary to reduce the torque ripples that cause undesirable acoustic noises, torsional vibrations, and shaft failures [4] [6].…”

“…MPC belongs to a short prediction horizon method covering only one sampling period. The MPC in the PMSM system can be divided into model predictive current control (MPCC), model predictive speed control (MPSC), and model predictive torque control (MPTC) according to the primary control objective [8][9][10]. A voltage smoother in [11] and an integral sliding mode disturbance observer in [12] are combined with the MPSC respectively to enhance control performances of speed or angular velocity.…”
