A Lookup Table Based Loss Minimizing Control for FCEV Permanent Magnet Synchronous Motors

Determining electrical losses of the traction drive of electric train based on a synchronous motor with excitation from permanent magnets

“…Reducing energy expenditure in the operation of a traction drive can be achieved by using new types of engines [5,6], inverter topologies [12], control systems [13], as well as by improving characteristics of existing systems, which is attained by various means. To assess the energy efficiency of…”

“…Papers [13][14][15][16][17] address the issue on determining losses in the engine. Authors of [13], based on the modeling of SMPM, compiled a table of losses in a traction engine, using which makes it possible to create a control system optimized for the engine's performance efficiency coefficient. Paper [14] proposed a model of losses in SMPM, taking into account losses in steel and copper; and reported a procedure, which makes it possible to determine with high accuracy the harmonic composition of the phase current.…”

Certainty equivalence adaptive speed controller for permanent magnet synchronous motor

“…The reasons are that the PMSMs have desirable features such as compact structure, high air-gap flux, high power density, high torque to current ratio, and high efficiency compared with induction motor because of the absence of rotor losses and lower no-load current below the rated speed [1][2][3]. However, the control performance of the PMSM drive system can be affected by the system non-linearity, motor parameters variations and external load torque disturbances [4].…”

Loss-based investigation and hybrid compensation of parameter variation effects on control of permanent magnet synchronous motors

“…Controlling the PMSMs can be performed via different control methods. Some of these methods such as i d = 0 or search‐based loss minimization control methods are independent of motor parameters . In contrast, in some methods, parameter identification has a great importance .…”
