Fault Tolerant Control of PMSM Drive Using Luenberger and Adaptive Back-EMF Observers

Abstract

In this paper, we propose to design a sensorless controller that can cope both with performance and robustness by the hybridization of two controllers. The strategy introduced in this paper includes the sensorless active fault tolerant controller of the PMSM drive at high speed. It is built with the combination of a vector controller, two virtual sensors: Luenberger and adaptive back-EMF observers, and a voting algorithm using Newton-Raphson method. Simulation results are provided to verify effectiveness of the proposed strategy of a 1kW PMSM motor driven by fault tolerant control in case of position sensor outage.

Synthesis of Fractional Order Fuzzy Observer for a Fractional Order Takagi-Sugeno Model With Unmeasurable Premise Variables

“…( 15) and ( 16 Theorem 1. The state estimation error between the noninteger order Takagi-Sugeno system (15) and the noninteger order fuzzy observer (16) asymptotically tends to zero if there exist two positive definite symmetric matrices 𝑃 and 𝑄, matrices 𝐺 𝑖 , and positive scalars  1 ,  2 , and  such that the following matrix inequalities are satisfied:…”

“…In systems delineated by Takagi-Sugeno models, the application of observer bank schemes for fault diagnosis encounters challenges due to the introduced couplings within the structure. Consequently, limited research endeavors have addressed the development of observers grounded in fractional-order fuzzy Takagi-Sugeno models [14][15][16].…”

Enhanced Reliability for Winding Machine via New Fault Tolerant Control Based on RST-Backstepping Controller

“…All the approaches to FTC can be categorised into two groups: active and passive (Elbakri and Boumhidi, 2020;Klimkowski, 2016;Medjmadj, 2019). The active approach requests a module for fault detection and isolation (FDI) in order to reconfigure the controller (Klimkowski, 2017).…”
