This article introduces an improved model predictive current control (MPCC) with the finite position set model reference adaptive system (FPS-MRAS) observer for speed sensorless control of an interior permanent-magnet synchronous motor (IPMSM). The voltage and current at the (k)th moment are used to calculate the back electromotive force (EMF), which will predict the current at the ( ${k} +1$ )th moment. Otherwise, the current delay compensation is introduced to further improve the dynamic performance and solve the delay problem. The FPS-MRAS is proposed to replace the traditional proportional-integral (PI) controller, which usually needs lots of work to tune the parameters. The discrete rotor position angles are used to calculate discrete stator fluxes, which are applied to form the cost function. An iterative algorithm with the binary circle is introduced to increase the estimation accuracy with finite angles. In the end, the dynamic performance of these methods is compared via experiments under different conditions.
