Abstract
The extended state observer (ESO) was applied in the sensorless single phase Stirling linear generator drives in this paper. The structure of the linear generator was introduced and mathematical model was built. To detect the mover position in the condition of position sensorless, the back-EMF ESO was deduced to calculate the position. This strategy was realized in the simulation and experiment. Compared with the normal state observer, in the conditions of noise and imprecision of generator parameters, ESO would improve the robustness of the system.
