This paper presents the application of a fuzzy-logic controller for an AC servomotor. The fuzzy-logic controller is coupled to conventional methods for AC Servo commutation, such as a field-oriented flux control and voltage amplifiers. A test bench platform was designed specifically to test the controller at different load values. The behaviour of the speed and torque variables got stable while...

The servomotor is an essential element in the automation of industrial processes, and its control is necessary to achieve better performance in applications of industrial positioning. In the systems control, the knowledge of plant model through proper identification is fundamental. This work presents a methodology based on neural networks to obtain the servomotors models on industrial applicati...

The goal of this laboratory activity is to design, implement and test a speed PI controller for the DC servomotor available in laboratory. The control design is carried out in frequency domain (i.e Bode’s method), using the nominal model of the DC gearmotor derived in the previous laboratory activity. Accurate numerical simulations are used to validate the control design, before moving on with ...

Since a snake achieves various movements just by a slender body, the mechanism of it is very amazing Many researches have been focusing on a snake like robot and have done for it on the ground. However the meander motion of the snake not only can be done by ground creatures, but also can be done by a water creature such as a sea snake or an eel. Therefore, the purpose of our research is to deve...

A novel servomotor design that is powered and controlled through only one wire is presented in this paper. A traditional servomotor needs both a power cable and a control cable connecting the motor to a control amplifier. Cables are bulky, heavy, and expensive and, more importantly, difficult to install and maintain in many applications. Particularly for multi-axis applications, like robots and...

AC servomotor speed or current controller based on PI control and/or optimal control, can not eliminate the cyclical fluctuations of speed or current when subject to periodic disturbances. However, repetitive control performs well when the disturbance is cyclical with constant period (frequency). For a PWM (Pulse Width Modulated) inverter driven AC servomotor, a time delay is inserted between t...

In this paper the design and implementation of a network for integrating Programmable Logic Controllers (PLC), the Object-Linking and Embedding for Process Control protocol (OPC) and the open-source Easy Java Simulations (EJS) package is presented. A LabVIEW interface and the Java-Internet-LabVIEW (JIL) server complete the scheme for data exchange. This configuration allows the user to remotely...
