Speed control of 3-PHASE induction MOTOR ( up to 3 KW, 2 pole ) using TEXAS INSTRUMENTS STELLARIS
LM3S811 (ARM CORTEX-M3 CORE) microcontroller.Induction MOTORS are the most widely used MOTORS for industrial control and automation..However, many applications need variable speed operations.Rotation speed of the shaft strongly depends on the AC frequency,and torque strongly depends on the AC current amplitude.Knowing this,a proper working open loop control can be realized by applying three sine waves with constant electrical phase shift of 120 degrees to each other-but with variable amplitude and frequency.The VOLTAGE/FREQUENCY ratio is maintained constant to provide a constant (MAXIMUM) torque over the operating range.The target speed has a lower boundary of 10 HZ and upper boundary of 60 HZ.The V/F function determines the drive amplitude corresponding to that frequency.The microcontroller can be easily programmed to provide up to three independent sine waves by using the PWM.Sine look-up table is created in the program memory (64 entries,16 bit signed integer format).After every TIMER overflow interrupt, the value pointed to by the offset registers on the sine table is read.The value read from the table is scaled based on the MOTOR frequency input by multiplying by the frequency input value to find the ratio of PWM ,with respect to the maximum DC bus (460 V).This value is loaded to the corresponding PWM duty cycle registers.Standard AC supply is converted to a DC voltage by using a 3-PHASE diode bridge rectifier. A capacitor filters the ripple in the DC bus.This DC bus is used to generate a variable voltage and variable frequency power supply.Since, the MOTOR windings are inductive, the incoming voltage will be integrated to produce a MOTOR current that is proportional to the PWM duty cycle.The power inverter has 6 switches that are controlled in order to generate an AC output from the DC input,PWM signals generated from the microcontroller control these 6 switches.The phase volgate is determined by the duty cycle of the PWM signals..In time, a maximum of three switches will be “ON”.When switches are “on”
,current flows from the DC bus to the MOTOR winding..PWM is required to control the duration of the switches “ON” and “OFF” times.Three PWM are required to control the upper three switches of the power inverter.The lower switches are controlled by the inverted PWM signals of the corresponding upper switch.3-PHASE bridge driver is INTERNATIONAL RECTIFIER IR21362 I.C(INTEGRATED IGBT switches DEAD-TIME control).3-PHASE INVERTER is VISHAY CPV364M4U.A potentiometer connected to ADC on the microcontroller determines MOTOR speed. Software is written in ARM CORTEX-M3 assembler language.
