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

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

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

WIDE RANGE BAND PASS FILTER
DESCRIPTION:
Third-Order Wideband Bandpass Filter
This circuit demonstrates the operation and characteristics of a wideband bandpass filter, constructed by cascading a second-order low-pass and a high-pass filter. As a result, a 300 Hz to 3 kHz bandpass voice filter is formed.
Experiments:
Set the function generator to 1 kHz and the oscilloscope's time base to 0.2 ms/DIV. Increase the input frequency, about 1 kHz at a time up to 4 kHz, constantl ....etc
