This simulation shows Vector Control for an interior Permanent Magnet Synchronous Motor (PMSM) during torque regulation.
The PM Synchronous Motor Drive is composed of four main parts: The electrical motor, the Three-phase Inverter, the VECT controller and the Speed Controller.
The electrical motor is a 288 Vdc, 100 kW PMSM. This motor has 8 poles and the magnets are buried (salient rotor's type).
The Three-phase Inverter is a voltage source inverter, controlled by PWM. This block is built using the Universal Bridge Block.
The VECT controller block computes the three reference motor line currents corresponding to the flux and torque references and then generates a corresponding PWM using a three-phase current regulator. When the nominal flux is required, optimal control is used in order to minimise the line current amplitude for the required torque. When a flux weakening is needed, the amplitude and the phase of the current are changed to extend the torque-speed operating range.
The Speed Controller is used in torque regulation mode. The normalized flux value is computed with the speed of the machine in order to perform a flux weakening control.
The Torque limitation block is used to prevent the limitation due to the torque-speed characteristic of this motor for a 288 Vdc source. When the internal machine's voltage reaches the inverter voltage (because the desired torque is too high for the motor's speed), the inverter becomes in saturation mode (the desired current cannot flow anymore into the motor). After this point, there will be a loss of current tracking which will decrease the motor current. This block is used to reduce the reference torque as a function of the motor's speed and the torque-speed characteristic in order to never operate in inverter saturation mode.
Motor torque, speed, power, currents and voltages signals are available at the output of the block.
