This paper presents an enhanced Flux Weakening (FW) control scheme for Permanent Magnet Synchronous Motors (PMSMs), focused on electric vehicle applications. The novelty of the proposed algorithm is the integration in a unified scheme of both the accelerator pedal as torque reference and the cruise speed limiter (CSL) as speed limit, without interfering between them until this limit is achieved. The dq-axis current references are calculated from the proposed algorithm by using a polar coordinate system and a per-unit system. The latter is based on the characteristic machine parameters which aim to ease and simplify the algorithm implementation. Moreover, it takes advantage of the smooth transition between the Low Back Electromotive Force (LBEF) zone and the FW zone thanks to a voltage loop which changes the current-vector angle. Another fundamental merit of the proposed scheme is its capacity to work in all the dq-plane throughout the Maximum Torque per Ampere (MTPA), Constant Torque (CT), Current and Voltage Limit (CVL), Maximum Torque per Voltage (MTPV) and Constant Speed (CS) strategies without switching the algorithm. Simulations and experimental results from a real exterior-rotor Interior Permanent Magnet Synchronous Motor (IPMSM) direct-drive emotorbike verify the effectiveness of the proposed method.

“…When operating in low speed region, signal injection methods can achieve great performance (Choi & Seok, 2008;Piippo, Salomaki, & Luomi, 2008;Shinnaka, 2008), while in high speed region, back-EMF or rotor flux-based sensorless algorithms are widely applied. Using PMSM mathematic model, one can calculate the rotor flux or back-EMF, then obtain rotor position and speed (Cendoya, Solsona, Toccaceli, & Valla, 2002;Chen, Liu, & Chen, 2010;Chen, Tomita, Doki, & Okuma, 2003;Chern et al, 2012;Genduso, Miceli, Rando, & Galluzzo, 2010;Harnefors & Nee, 2000;Kim, Choi, Lee, & Lee, 2011;Morimoto, Kawamoto, Sanada, & Takeda, 2002;Yuan et al, 2013). But in real world, there may be sampling DC offset and parameters variation, thus a main problem in sensorless control is how to get accurate rotor speed and position under such conditions.…”

This article presents a sensorless control approach of salient PMSM with an online parameter identifier. Adaptive Integrator is proposed and utilised for the estimation of active flux and rotor position. As a result, integrator overflow caused by DC offset is avoided. Meanwhile, an online stator resistance identification algorithm using strong tracking filter is employed, and the identified stator resistance is fed back to the estimating algorithm. Thus, the estimating algorithm can calculate the rotor position correctly. Simulations and experimental results validate the feasibility of both adaptive integrator and the parameter identification method.

Position sensorless control has been widely studied for electrical rotor position estimation. However, because of the magnetic periodicity, mechanical rotor position sensorless control of multi-pole electric machine was hardly reported. By increasing the control dimensions, this paper proposes novel machine topologies named as Dual-gap Dual-pole Composite Machines (DDCMs), where the mechanical rotor position can be demodulated from the electrical rotor positions of two air gaps. The machine topologies and corresponding control theory are elaborated, and one of the topologies is selected as the primary prototype, which is composed of a Permanent Magnet Synchronous Machine (PMSM) with 6 poles and a Variable Reluctance Resolver (VRR) with 4 poles. Detailed design and analysis on the prototype along with the control strategy are presented. Finally, experiments are carried out based on the prototype to verify the feasibility of the proposed methodology. 
