Due to the increasing electrification of automotive drive train systems, accurate position and speed sensors play an important role to achieve an optimum drive train performance and driving range. These sensor systems determine the rotor shaft position to deliver exact data for efficient drive train control. The system itself must be reliable, sufficiently accurate and cost efficient at the same time. In this way, the design process of the sensor system is influenced by a trade-off, which influences the system performance in view of different parameters, e.g., resolution and data processing accuracy. The focus of the present work is to introduce a method for benchmarking the performance of not only the rotor shaft position sensor, but the whole electric drive train sensor systems by use of a highly accurate reference system on a specifically developed test bench. To achieve a significant benchmark statement by determination of the rotor position angle error, the independent measuring systems, the automotive drive train system and the reference system are synchronized by the use of a common trigger/clock signal. The mentioned signal defines the time steps of the system under test rotor position angle capturing procedure and those of the reference system simultaneously. This enables a common time-base for two independent working measurement systems. This publication provides information about a concept for enhanced rotor position sensor evaluation that enables the merging of real-time data processing with test bench measurement. This procedure provides an important basis for the selection and optimization of position sensor systems for sophisticated electric powertrains.

Sensorless technique becomes popular nowadays in electrical drive applications specificially for AC motor drive. It is applied to determine and estimate the rotor position especially for PMSM motor. This paper presents the comparison sensorless technique to determine and estimate the position and rotor of PMSM motor. PMSM motor is widely used in industrial and automation due to its high performance motor drive. However, the location of PMSM motor in humidity and harsh environment causing the accuracy of motor is inaccurate due to deterioration of position sensor . Therefore, many sensorless techniques have been proposed by previous researchers in order to solve the problem. This paper presents the review of several categories; Model Based Method, Saliency Based Method and Signal Injection, and Artificial Intelligence Based Estimator. In addition, sensorless techniques on each category have been compared and described in terms of their advantages and disadvantages.
