This paper proposes an adaptive positioning control of servo system using position sensorless controlled interior permanent magnet synchronous motor (IPMSM), in which the proposed adaptive system is based on the combination of Dynamic Certainty Equivalence (DyCE) principle and the rotor position estimation method of IPMSM with comb filters. Generally, the positioning servo system is out of the strictly...
This paper proposes a new flux estimation for permanent magnet synchronous motor sensorless control using all-path filters and band-pass filters as quasi-integrators, which can enhance the flux linkage estimation performance using all-path filters and low-path filters that the authors have already proposed. This paper also presents extremely precise rotor position estimation performances in the low-speed...
This paper proposes a direct rotor-position estimation method for IPMSMs (Interior Permanent Magnet Synchronous Motors) in low-speed regions including standstill. Proposed estimation method does not require phase-locked-loop (PLL) which degrade the response of position estimation and it can improve the response of position estimation.
This paper proposes fast initial position estimation of IPMSMs (Interior Permanent Magnet Synchronous Motors), which is based on intentional pulse voltage injection and comb filters. Most initial position estimation methods utilize the amplitude or differential values of high-frequency currents and the performance of sensorless control depends on the algorithm to reconstruct these values. Although...
This paper proposes the fast initial position estimation of IPMSMs (Interior Permanent Magnet Synchronous Motors), based on intentional pulse voltage injection and comb filters. Generally, the rotor position can be estimated by detecting high-frequency current caused by injected high-frequency voltage because its response includes inductance information due to saliency. In general, sinusoidal current,...
This paper proposes an extended-flux model with core-loss resistance of synchronous reluctance motors (SynRMs) and precise torque estimation without core-loss measurement and position encoder. The proposed torque estimation is useful for precise maximum torque per ampere (MTPA) control of position sensorless controlled SynRMs, which is achieved with the assistance of active and reactive powers.
