Inductance Based Sensorless Control of Switched Reluctance Motor
This paper presents a sensorless control of switched reluctance motor (SRM) driven by the four phase asymmetric bridge inverter. In this method to obtain the rotor position of switched reluctance motor by means of resonant circuit method. The resonant circuit comprising of the motor and the power electronic converter, motor phase inductance and the parasitic capacitance of converter switches. F...
متن کاملA Low Cost Sensorless Control Drive Circuit for of Low Voltage Switched Reluctance Motor
Shaft position sensing is an essential part of switched reluctance (SR) motor drive In order to synchronize the pulses of phase current with the period of rising inductance of the proper motor phase. Direct sensors such as, Hall effect and optical encoder are commonly used in SR motors. The purpose of this paper is to present an indirect shaft positioning sensing known as "sensorless " control ...
متن کاملFuzzy Logic Control of a Switched Reluctance Motor
Because of extreme local saturation at pole tips of excited phase and uncircular shape of rotor and stator, a Swithed Reluctance Motor (SRM) does not have a simple and accurate mathematical model. Therefore, the output control of this motor requires a robust controller which is not based on an accurate model of the process. Fuzzy controllers, to some extent, will satisfy these requirements. Tet...
متن کاملRotor Position of Switched Reluctance Motor Using Sensorless Method
Switched reluctance motor (SRM) is an energy converter that converts an electrical energy to mechanical energy in motoring operation and vice-versa in generating operation. When the rotor is out of alignment, the inductance is very low and the current also increase rapidly. The rotor is aligned with the stator then the inductance become very large. In the simulation results, how the rotor minim...
متن کاملA New Sensorless Method for Switched Reluctance Motor Drives
This paper describes a new method for indirect sensing of the rotor position in switched reluctance motors (SRM’s) using pulsewidth modulation voltage control. The detection method uses the change of the derivative of the phase current to detect the position where a rotor pole and stator pole start to overlap, giving one position update per energy conversion. As no a priori knowledge of motor p...
