Implementing Embedded Speed Control for AC Induction Motors



Physics of Induction Motors

•Current passing through a conductor creates magnetic field–Direction of magnetic field is determined by the right hand rule•Changing magnetic field produces current in a conductor–Direction of current is determined by right hand rule•Electromagnetic Induction–Changing current induces changing magnetic field around it. –A conductor placed in this field has induced current and induced magnetic field•Inte ....etc

PLC-Based Monitoring Control System for Three-Phase Induction Motors
The article presents a monitoring and control system design and implementation for the three-phase induction motor based on programmable logic controller (PLC) technology. the operational parameters of the motor is correlated with the the speed requested by the user by the PLC. This is done in both the during normal operation and under trip conditions. Tests prove that a higher accuracy in speed regulation is provided by the induction motor system driven by inverter a ....etc

ABSTRACT
A novel sensorless adaptive robust control law is proposed to improve the trajectory tracking performance of induction motors. The proposed design employs the so called vector (or field oriented) control theory for the induction motor drives and the designed ....etc

CAN-based Synchronized Motion Control for Induction Motors

Abstract:

A control area network (CAN) based multi-motor synchronized motion control system with an advanced synchronized control strategy is proposed. The strategy is to incorporate the adjacent cross-coupling control strategy into the sliding mode control architecture. As illustrated by the four-induction-motor-based experimental results, the multi-motor synchronized motion control system, via the CAN bus, has been successfully implemented. With the emplo ....etc

Abstract:
The field oriented control emerged as an important approach for the control of AC machines, and continues to be explored and developed in the literature. The estimation of the rotor flux from the measurable variables was the only method used to implement the vector control of the induction machine. To replace the estimator based on the mathematical model of the system, which can lead to unintended errors due to uncertainties on the model and on the measures we use an appropriate observer.

Abstract - Some form of simple control is needed for small induction motors. This paper proposes a simple speed control method for small induction motors using a simple calculation without the need for a speed sensor. In this method, the load torque is estimated from the detected power factor of the induction motor and the speed of the induction motor is compensated for by a frequency-boost technique. The boost frequency is selected from a data table measured before hand. Sa ....etc
