Robust Torque Control of Internal Permanent Magnet Motor Using Experimental Flux Maps

As the industrial and transportation fields are moving towards electrification, electrical motors are facing increasingly stringent requirements, resulting in accelerated degradation due to parameter variation and component aging. This paper proposes an advanced electric motor torque control strategy robust against the motor parameter variations due to environment and aging. Therefore, to mitigate the adverse effects of these variations, the proposed control strategy leverages multidimensional lookup tables to generate the current references for a standard current vector control. In particular, this paper investigates the impact of motor parameter variations on traditional torque control methods and compares them with a new robust control strategy. The results demonstrate the importance of robust control techniques in electric motor control systems, particularly in demanding applications such as automotive and motorsport.
