This study proposes a novel rotor position estimation method for wound-rotor synchronous starter/generator (WSSG). At the starting stage, WSSG needs a resolver to obtain the main machine's (MM's) rotor position. However, the use of resolver increases starting system's complexity, volume, weight and cost. In order to solve this problem, a novel kind of MM's rotor position estimation method is proposed, which considers the structure of WSSG as a resolver. The novel method injects a rotating voltage into MM's stator, detects main exciter's stator current and subsequently processes the current signals to estimate MM's rotor position. Experimental results show that the novel method can estimate rotor position accurately, which are in good agreement with the theoretical analyses and simulation results. Compared to the saliency tracking rotor position estimation method, the novel method does not rely on WSSG's parameters (including MM's saliency), and the signal processing procedures are more simple.

This paper deals with a stator-flux-oriented control method for permanent-magnet (PM) synchronous motors and synchronous reluctance motors (SyRMs). The stator-flux magnitude and the torque-producing current component are the controlled variables. This choice simplifies the references calculation (as compared to the current control in rotor coordinates), but the dynamics seen by the inner control loops become nonlinear and coupled, potentially compromising the control performance. We propose an exact input-output feedback linearization structure and a systematic design procedure for the stator-flux-oriented control method. Simulation and experimental results are presented to verify the dynamic performance of the designed controller using a 6.7-kW SyRM drive.

These requirements Conference version "Position estimation for synchronous motor drives: Unified framework for design and analysis" was presented at the 2017 IEEE International Symposium on Sensorless Control for Electrical Drives (SLED), Catania, Italy, Sep. [18][19]. This work was supported in part by ABB Oy and in part by the Academy of Finland.…”

Tuovinen, T. (2018)Abstract-This paper deals with the speed and position estimation for synchronous reluctance motors (SyRMs) and interior permanent-magnet synchronous motors (IPMs). A unified design and analysis framework for a class of back-electromotive-force (back-EMF)-based observers is developed and the links between apparently different estimation methods are brought out. State observers equipped with a speed-adaptation law are shown to be mathematically equivalent to voltage-model-based flux observers equipped with a position-tracking loop. The error signal driving the adaptation law or the tracking loop is presented in a generalized form. Using the framework, a stabilizing gain design is reviewed and detailed design guidelines are given. Selected observer designs are experimentally evaluated using a 6.7-kW SyRM drive and a 2.2-kW IPM drive.
