Position Sensors Fault Tolerant Control System in BLDC Motors
Developing of fault tolerant control systems (FTCS’s) for permanent magnet Brushless DC (BLDC) motor drives to diagnose and handle various faults have been of the research concentrations in the last decade. In this paper a novel fault diagnosis algorithm for position sensors (Hall Effect sensors) failure of the BLDC motor is presented. Fault detection and identification of Hall Effect sensors a...
متن کاملForward Position Kinematics of a Parallel Manipulator with New Architecture
The forward position kinematics (FPK) of a parallel manipulator with new architecture supposed to be used as a moving mechanism in a flight simulator project is discussed in this paper. The closed form solution for the FPK problem of the manipulator is first determined. It has, then, been shown that there are at most 24 solutions for FPK problem. This result has been verified by using other tec...
متن کاملFault Diagnosis and Fault-tolerant Control of Position Sensors for Switched Reluctance Motors
Position sensor is the key of exact commutation for switched reluctance motor (SRM). When position sensor is faulted, some phase information of commutation will be lost, causes torque decrease, affects the system reliability. Through the analysis of the fault position signals, a real-time diagnostic method that detected the edge sequences of position signals and calculated the angle between the...
متن کاملLow cost sinusoidal control of BLDC motors with Hall sensors using ST7FMC
BLDC motors are the workhorses in most light industrial applications. In some cases, Halleffect position sensors are used to simplify control logics for controlling these motors. BLDC motors, by the nature of currents through them, are somewhat noisy and a little less efficient. These disadvantages plus the cost of sensors are an integral part of these drive systems. However, if the motor can b...
متن کاملSensorless position control of induction motors-an emerging technology
Concepts for sensorless position control of induction motor drives rely on anisotropic properties of the machine rotor. The built-in spatial anisotropy is detected by injecting a high-frequency flux wave into the stator. The resulting stator current harmonics contain frequency components that depend on the rotor position. Models of the rotor saliency serve to extract the rotor position signal u...
