Howto Motor Torque Control

Other Parts Discussed in Thread: TMS320F28335, CONTROLSUITE

my environment

TMDSHVMTRPFCKIT + HVACIMTR-AC Induction Motro + TMS320F28335 controlCARD

source : Controlsuite -> Motor -> High-voltage Motor Control + PFC Kit -> Example projects -> ACI:FOC Sensorless for Delfine F2833x -> LEVEL2

Question 1)

i want control torque and speed under Open Loop Operation ( Do not use AD conversion and shunt resistor )

i think idRef is speed control, iqRef is torque control

but level2 is not exist idRef and iqRef

VqTesting, VdTesting -> what is it?

Question 2)

i want to change ISR_Frequency 10khz -> 2khz

#define ISR_FREQUENCY 2 -> motor not run

how can i do it?

Hi ChunLei,

I did a DTC in the f28335, but I haven`t reached the results I expected, have you tried something?

how do you plan to control torque without measuring torque (current) in your open loop control?

I never said I am not measuring current. I implemented a classical DTC.

I just wrote in this post to exchange experiences with another peaple who are developing DTC control on IM. Do you Know if there is a post of DTC developers?
