Adaptive quasi-proportional resonant control with parameter estimation for PMSM sensorless control
Advances in Mechanical Engineering, 2023 Conventional sliding mode control (SMO) utilizes a sign function and a low-pass filter (LPF) to achieve sensorless control of a permanent magnet synchronous motor (PMSM). However, the introduction of the sign function generates a large number of high harmonics, resulting in a significant system output chattering, whereas the addition of the LPF ...

NPC photovoltaic grid-connected inverter using proportional-resonant controller [PDF]
2014 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC), 2014 Multi-megawatt photovoltaic (PV) power plants are widespread in electrical power systems because of the drastic decrease in the PV panel prices. The multi-string structure is considered for high power PV systems due to the increase in the overall energy conversion efficiency and the modularity when compared to the centralized topology.
