Mechanical sensorless position and speed control of non-saillent permanent magnet synchronous machine : Application to an electromechanical actuator for aileron
type: Dataset
description: The issue of sensorless control of permanent magnet synchronous machine (PMSM) has been well studied in the field of automation and electrical engineering. In the following work, we were interested in the peculiar problem of low-speed sensorless control of surface PMSM. The objective is to o er a new method for the position control of an industrial electro-mechanical actuator, considering an aeronautical context (a flap actuator). First, modeling and observability analyses of surface (non-salient) PMSM and interior (salient) PMSM have been studied. A loss of observability can be especially found at low speed for models of non-salient machines. To overcome this loss, we have developped new models, that take into account vibrations caused by a signal injection. A theoretical observability study of these latter models shows that observability is now guaranteed for the whole speed range, including standstill. We thus proposed an estimation method of the position and speed of the PMSM, based on these models, with a dedicated injection signal. Unlike sallient-based methods that are only valid for sailent machines, our approach can be used with all types of PMSM. An Extended Kalman Filter is used to observe the position, speed and eventually the load torque. The proposed approach was validated on a dedicated test bench. Many simulation and experimental tests were performed on an industrial-oriented benchmark. Results showed the performances, robustness and limitations of the proposed observers. We have also studied speed sensorless control of the machine. Indeed, two observer syntheses have been presented. The first one is based on robust synthesis of an LPV observer using a polytopic approach. The second method is an adaptative-gain second-order sliding mode observer. Experimental feasibility of the two methods has been demonstrated.
