Robust Sliding Mode Speed Controller-based Model Reference Adaptive System (MRAS) and Load Torque Estimator for Interior Permanent Magnet Synchronous Motor (IPMSM) Drives

Sliding mode‐based velocity and torque controllers for permanent magnet synchronous motor drives system

“…Hosseini and Tabatabaei [5] develop a two‐loop approach for interior permanent magnet synchronous motor (IPMSM), a conventional velocity proportional integral (PI) controller in the outer loop, and an adaptive fractional order sliding mode controller (SMC) in the inner loop. Zaky [6] develops a two‐loop approach for IPMSM to improve the dynamic performance, applying a robust sliding mode control‐based model reference adaptive system with load torque estimator in the outer loop. To improve the anti‐disturbance ability and reduce the torque ripples of the PMSM servo system, Liu proposes a robust iterative learning control (ILC) scheme by an adaptive SMC [7].…”
