How to control speed of three phase induction motor?

Abstract— There are different method of speed control of three phase induction motor and to control the speed of three phase induction motor generally using V/F control strategy.

Can a PI controller control the speed of a three-phase induction motor?

Many speed control techniques exist in literature but this paper presents the design of a simple PI controller and its use to control the speed of a three-phase induction motor. A controller design that applies the Phase margin (PM) as the stability criterion is employed.

How to control speed of induction motor?

While there are methods of speed control of induction motor, Variable Voltage Variable Frequency or V/F is the most ordinary method of control. This method is most suitable for applications with no position control requirements or the need for high precision of control.

What types of inverters are used in variable speed induction motor drives?

There are two fundamental classifications of inverters used in variable speed induction motor drives: current-source inverters and voltage-source inverters. A current-source inverter is more suitable to high power levels. Most smaller drives utilize a voltage-source inverter, of which the pulse width modulated (PWM) inverter is popular.
