Improved Speed Estimation in Sensorless PM Brushless AC Drives
The application of flux-observer-based sensorless control to permanent-magnet brushless ac motor drives is described. Current methods of speed estimation are assessed, both theoretically and experimentally, and an improved method, which combines the best features of methods in which speed is derived from the differential of rotor position and from the ratio of the electromotive force to excitat...
متن کاملBrushless AC Drives
The accuracy of rotor position estimation in the (several kHz), and its amplitude cannot be changed as it is conventional signal injection based sensorless control of determined by the DC-link voltage and the PWM duty cycle, permanent magnet brushless AC drives depends on the load the amplitude of high frequency current will be too small for current. This paper proposes an improved method, whic...
متن کاملDevelopment of a Speed Sensorless IM Drives
The primary objective of this paper is to elimination of the problem of sensitivity to parameter variation of induction motor drive. The proposed sensorless strategy is based on an algorithm permitting a better simultaneous estimation of the rotor speed and the stator resistance including an adaptive mechanism based on the lyaponov theory. To study the reliability and the robustness of the sens...
متن کاملSensorless Speed Control of Brushless DC Motor with Fuzzy Based Estimation
This paper describes a simple way to control the Brush Less DC Motor (BLDCM) for electrical applications. To control this machine it is generally required to measure the speed and position of rotor by using the sensor because the inverter phases, acting at any time, must be commutated depending on the rotor position. The position sensors make the motor system more complicated and mechanically u...
متن کاملPerformances Comparison of Neural Architectures for On-Line Speed Estimation in Sensorless IM Drives
The performance of sensor-less controlled induction motor drive depends on the accuracy of the estimated speed. Conventional estimation techniques being mathematically complex require more execution time resulting in poor dynamic response. The nonlinear mapping capability and powerful learning algorithms of neural network provides a promising alternative for on-line speed estimation. The on-lin...
