PMSM simulation

The simulink model of current controlled PMSM drive with constant torque control id=0.

Description

The simulation model contains the current controlled PMSM drive with 2-level SPWM and the 3-phase universal converter with dc bus system.
The mathematical model of motor is developed using park transformation matrix, which transformed the 3-phase variables abc into steady state dc signals dq0.
The PMSM drive system has double loops, the inner the current control and the outer loop with speed control. The simplest vector control is when id value is assumed zero (constant torque control ), in which the motor will operate efficiently upto rated speed.

• Required Products: Simulink
• MATLAB release: MATLAB 7.13 (R2011b)

[Cheku Dorji]

Hi MHz, plez refer literature on machine drives control system for clarification.

[MHz]

Hi Cheku Dorji,
why output of PI controller is iq ref,while input's is speed error?
