In a sensorless motor speed control system, the is not directly measured using sensor, but it estimated an observer. The systems are mostly applied to AC motors, while they have been widely DC motors. Therefore, this paper presents simple observers estimate speed. used were based on electric equation. Two methods in research. first method was observer estimating resistance inductance values (L-...
For studying the traffic safety of high-speed railway, this research considers high-quality second-level wind speed data as its basis. However, quality can be greatly lowered by disturbances during collection and storage. Therefore, it is crucial to control Wind along railway are unstable non-linear. In order adapt characteristic, study combines a convolutional neural network (CNN), long short-...
<p>Electrical submersible pumps (ESPs) are multistage centrifugal driven by specially designed three-phase induction motors. They used in many applications such as nuclear and petroleum industries. In the presented paper, we study speed control of an ESP pump using a rule-based fuzzy logic controller (FLC). As case study, oil well is considered to analyze effects changing on both motor pa...
