Control of Permanent Magnet Synchronous Motor Based on Adaptive Super-Twisting Sliding Mode Observer and Improved PSO
To mitigate the chattering and limited adaptability of conventional sliding mode observers (SMOs) in position sensorless control for permanent magnet synchronous motors (PMSMs) across a wide range of operating conditions, a control strategy based on an adaptive-gain super-twisting sliding mode observer (AST-SMO) combin...
