Abstract:

An incremental shaft encoder has been designed and developed for measuring angular velocity of a shaft. The construction of the circuit was achieved using disc of a plastic materials with fifteen slots. Infrared light emitting diode, comparator, photo transistor (sensor), 555 timer, encoder, decoder, differentiator (control logic) and display. Bubble resolver was also included in the circuits to eliminate ± 1 counting error which is inherent in most digital device. The incremental shaft encoder designed and developed was able to measure maximum speed of 2500rpm and the corresponding frequency

Abstract:

Optical encoders are widely used in accurate displacement measurement and motion-control technologies. Based on different measurement methods, optical encoders can be divided into absolute and incremental optical encoders. Absolute linear encoders are commonly used in advanced computer numerical control (CNC) machines. The subdivision error within one signal period (SDE) of the absolute linear encoder is vital to the positioning accuracy and low velocity control of CNC machines. In our paper, we study the working principle of the absolute linear encoder. We proposed two methods for reducing th

Abstract:

Incremental rotary encoder is a sensor that can be used to measure the degree of rotation in ship steering simulations. To create a ship steering simulation, Visual Basic software was used to simulate the movement of the rudder and ship. Meanwhile, to obtain incremental rotary encoder reading data, serial communication is used via Universal Serial Bus (USB) media bridged by Arduino which is programmed to convert incremental sensor signals into ASCII signals with a bolt rate of 9600 bps. The aim of this research is to test the accuracy level of the incremental rotary encoder sensor in ship stee

Abstract:

Base on the structure of the mechanical rotary encoder, the characteristics of the glitches and the effective waveform are analyzed. A new algorithm for removing the glitches and accurately counting is introduced. The core idea of the algorithm is to check the output of the phase-lag part when the output of the phase-advance port changes. This algorithm can accurately remove the glitches form the signal and count exactly. This method for glitches removing is very convenient, without additional cost and efficient for rapid rotation.

Abstract:

Anomaly detection for core temperature has great significance in maintaining the safety of nuclear power plants. However, traditional auto-encoder-based anomaly detection methods might extract the latent space features with redundancy, which may lead to missing and false alarms. To address this problem, the idea of feature disentangling is introduced under the auto-encoder framework in this paper. First, a feature disentangling auto-encoder (DAE) is proposed where a latent space disentangling loss is designed to disentangle the features. We further propose an incrementally feature disentanglin

This paper proposes a new algorithm using signals from an incremental encoder for estimating a rotating shaft's speed. This algorithm eliminated the oscillations appearing in classical fixed-time and fixed-space algorithms, even when speed was constant. A fixed-time algorithm measures angular displacement at fixed-time intervals, while a fixed-space algorithm measures time every fixed-angular displacement. Time and displacement measurements were used to generate estimations for speed. The new algorithm generated a unique value for estimating speed due to synchronising encoder pulses and a sign

In vector-controlled Permanent Magnet Synchronous Motors (PMSMs), measuring the motor flux angle, particularly the rotor position, is essential.

Abstract:

Variable-speed electrical drive control typically relies upon a two-loop scheme, one for torque/speed and another for stator current control. In modern drive control methods, the actual mechanical speed is needed for both loops. In practical applications, the speed is often acquired by incremental rotary encoders. The most used method derives speed from an encoder pulse count during a fixed amount of time. It is known that this sensing method produces time delay in the speed feedback loop as well as fluctuations in the speed measurements. Time lags produce phase loss that has potentially negat

Abstract:

Three-phase brushless motors are an indispensable part of the industry. A significant portion of electricity consumption is the energy consumed by industrial motors. Therefore, these electric motors need to be used efficiently. If these motors are not driven by the suitable inverter, they cannot handle the load or increase losses in the energy. In addition, the system can be inefficient.  Since these motors have a high starting torque and controlling rotation speed is difficult, a better control method is preferred rather than a V/f control.        &nbsp

Abstract:

The photoelectric encoder is a kind of encoder that uses high-precision metrology grating as the detection element to convert the input angular position information into corresponding digital signals through the photo-electric conversion device. It has the advantages of high resolution and wide measuring range, so it is widely used in precision angle measuring devices and high-precision speed regulating systems. In this study, an incremental photoelectric encoder is used, and a receiving system of vertical incidence is chosen, covering a photocell receiving circuit and an infrared circuit. The

Abstract:

The incremental optical encoder is widely used in PMSM servo system for speed detection. However, this method is detected the average speed, which will cause delay time, and make the speed control system unstable at low speed range. A speed observer was designed in this paper, which is combining state observer and Kalman filter to estimate instantaneous speed. Simulation results show that this method can improve the speed detection accuracy of the PMSM servo system.
